Install programs which require interaction, like a confirmation step, a new password or user interaction of some sort.
* mysql-server, for the webserver in localhost, etc.
* phpmyadmin, to manage mysqldatabases easily through a web browser
* apachetop, for monitoring apache in real time
* ttf-mscorefonts-installer, required by other packages (PlayOnLinux, maybe?)
* a few others like java, and network filesystem network packages

If you need a webserver & php/mysql:
{CODE(colors="bash", wrap="1", caption="Command on a console")}sudo apt-get install -y mysql-server phpmyadmin apachetop postfix tasksel
sudo tasksel install lamp-server
sudo mysql_secure_installation
{CODE}
if you don't run the -+mysql_secure_installation+- command, mysql root will not have password set yet, and you won't be able to access mysql through phpmyadmin yet.
But for some reason, Ubuntu 18.04 comes with a different way to autheticate the root mysql user, and you may end up with problems to login to mysql with the password you just indicated in the steps above. Therefore, if that is your case also, you may need to run these steps to setup mysql root password as usual in earlier Ubuntu LTS versions:
https://linuxconfig.org/how-to-reset-root-mysql-password-on-ubuntu-18-04-bionic-beaver-linux
You can then install all the rest of the required and useful software for common tasks (including video editing, screencasting, etc). Note that the first package names until wcatalan are localization packages for our local language, and you can skip them or adapt for your language, etc.

Per omissió, Ubuntu 18.04 ve amb R 3.4.x. Però en els passos previs d'aquestes instruccions, s'han afegit ja els repositoris per a que la instal·lació d'R es faci amb la versió 3.5.x, que porta algunes millores interessants, desenvolupades inicialment a la branca [https://svn.r-project.org/R/branches/ALTREP/ALTREP.html|ALTREP] d'R.
Per poder instal·lar adequadament paquets d'R des de dins de la consola d'R et caldran paquets extra de sistema. I t'aniran bé algunes eines habituals associades (git, svn, etc). Pots posar les dependències habituals amb:
{CODE(colors="bash", wrap="1", caption="Command on a console")}sudo apt-get install -y r-recommended r-cran-xml libgraphviz-dev libcairo2-dev r-cran-cairodevice freeglut3 freeglut3-dev r-cran-rglpk r-cran-rgl r-cran-misc3d libx11-dev libxt-dev libcurl4-gnutls-dev libxml2-dev r-cran-xml libgraphviz-dev libcairo2-dev bwidget tk-table libv8-dev r-cran-rjava libmpfr-dev libc6 libssl-dev texlive-latex-extra texlive-lang-spanish libx11-dev libxml2-dev libxml2:i386 libxt-dev r-cran-misc3d subversion git texmaker tk-dev unaccent xvfb libgdal-dev libproj-dev r-cran-rmysql libmagick++-dev r-cran-rcolorbrewer r-cran-doparallel libssh2-1-dev libudunits2-dev libgdal-dev libgeos-dev libproj-dev libjq-dev libprotobuf-dev protobuf-compiler libssl-dev libcairo2-dev libglpk-dev dos2unix pandoc r-cran-rmio r-cran-gstat r-cran-maps r-cran-mapdata r-cran-ncdf4 r-cran-sp r-cran-raster r-cran-geor r-cran-ggmap r-cran-leaflet r-cran-rjags r-cran-snow r-cran-ggplot2 r-cran-igraph r-cran-lme4 r-cran-devtools r-cran-roxygen2 r-cran-rjava r-cran-xlsx
{CODE}
Una llista de paquets habituals d'R que et pot interessat tenir instal·lats de partida (un cop inicies una sessió d'R) són:
{CODE(colors="r", ln="1", caption="Command on an R console")}install.packages(c("devtools", "plotly", "Nozzle.R1", "VennDiagram", "stringr", "xml2", "data.table", "doParallel", "xtable", "plyr", "dplyr", "reshape2", "rjson", "d3heatmap", "htmlwidgets", "googleVis", "doMC", "knitr", "checkpoint", "XLConnect", "sem", "rmarkdown", "relimp", "effects", "aplpack", "flexdashboards", "addinslist", "tidyverse", "magick", "webshot", "pacman", "officer", "flextable", "huxtable", "rio", "sf", "png", "rsvg", "xml2", "sparklyr", "rgdal", "rosm", "tmap")){CODE}
Si estàs actualitzant des d'una versió d'R anterior, et poden ser útils aquestes instruccions de terminal de sistema:
{CODE(colors="bash", ln="1", caption="Command on a console")}sudo chmod 777 /usr/lib/R/site-library /usr/lib/R/site-library/* -R
sudo chmod 777 /usr/lib/R/library /usr/lib/R/library/* -R
sudo chmod 777 /usr/share/R/doc/html/* -R
{CODE}
I aquestes altres de consola d'R:
{CODE(colors="r", ln="1", caption="Command on an R console")}update.packages(ask = F, lib="/usr/lib/R/site-library", checkBuilt = TRUE)
{CODE}
Cal tenir present que per omissió RStudio demana la contrasenya de Gitlab/Github cada vegada que vols fer un -+push+- dels commits locals cap
Per omissió RStudio demana la contrasenya de Github cada vegada que vols fer un -+push+- dels commits locals cap a un repositori remot (com ((Gitlab)) o altres). Per que no ho demani cada vegada, pots dir-li que empri l'anell de claus del sistema per a recuperar les credencials git, amb les següents instruccions:
{CODE(colors="shell" ln="1" caption="Instruccions en terminal")}sudo apt-get install libgnome-keyring-dev
sudo make --directory=/usr/share/doc/git/contrib/credential/gnome-keyring
git config --global credential.helper /usr/share/doc/git/contrib/credential/gnome-keyring/git-credential-gnome-keyring
{CODE}
Thse instructions will save you some headache in a multi-boot environment when one OS changes the boot menu and doesn't allow you boot in your preFfered OS. You can boot from an Ubuntu live CS/DVD/USB, and install boot-repair program from its own repo, with:
{CODE(colors="shell" ln="1")}sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair
{CODE}

Usual R packages that are useful in many cases. You can install them in an R console in a terminal (Type "R" in the terminal to launch the R console), or through RStudio command line.

Ubuntu 18.04 comes with php 7.2, and some php applications might still fail with php 7.2 .Therefore, in some cases, it might be sensible to have both php 7.0 and php 5.x, so that you can choose which version to use for your needs at any time. Or even better, 7.1. You need to add a new repository to have other versions of php available, and you will require the equivalent branch for a patched apache2 that will work with the other php version repository.
You can do so with:
{CODE(colors="shell")}xavi@computer# sudo su
root@computer# add-apt-repository ppa:ondrej/php
root@computer# add-apt-repository ppa:ondrej/apache2
root@computer# apt-get update

{CODE}
Eventually Installing both php5.6 & php7.* resulted in a lot of complaining from apt and lots of conflicts. The first suggested resolution was to remove all the stock php5 packages so that PHP 5.6 could be installed - so I just accepted the first suggestion.
The config files are all in /etc/php/5.6 and /etc/php/7.* respectively - inside here is where you can configure which extensions are loaded, set the ini settings, and everything else for each version in isolation.
So to switch from php 5.6 to php 7.2 you need to do two things:
{CODE(colors="shell")}# For php in web apps
user@computer:/# sudo a2dismod php5.6; sudo a2enmod php7.2; sudo service apache2 restart
# For php-cli in the command line
user@computer:/# sudo ln -sfn /usr/bin/php7.2 /etc/alternatives/php
user@computer:/# php -v
# PHP 7.2.x (...)
# Copyright (c) 1997-2016 The PHP Group
# Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
{CODE}
or from php7.2 to php5.6:
{CODE(colors="shell")}# For php in web apps
user@computer:/# sudo a2dismod php7.2 ; sudo a2enmod php5.6 ; sudo service apache2 restart
# For php-cli in the command line
user@computer:/# sudo ln -sfn /usr/bin/php5.6 /etc/alternatives/php
user@computer:/# php -v
# PHP 5.6.21-1+donate.sury.org~xenial+2 (cli)
# Copyright (c) 1997-2016 The PHP Group
# Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
# with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
{CODE}
From the commandline, I have both php5.6 and php7.2 available as commands. I also still have a php command - look in /etc/alternatives to see that it symlinks to a particular version of PHP cli*. You can also quickly check which yours is using by running php -v.
Remember that php.ini and other files with settings are not in /etc/php5 anymore but in /etc/php/__version__/
You may use a nice (but closed source) IDE such as PHPStorm (which provides a version at no cost for FLOSS projects such as Tiki), or stick with pure FLOSS apps such as Aptana Studio IDE.

Shutter seems to be missing some perl dependencies in repositories to have the edit feature installed by default. You can add packages by hand (they work fine) with:
{CODE(colors="shell" ln="1" caption="Commands in a terminal")}cd ~/tmp
wget https://launchpad.net/ubuntu/+archive/primary/+files/libgoocanvas-common_1.0.0-1_all.deb
wget https://launchpad.net/ubuntu/+archive/primary/+files/libgoocanvas3_1.0.0-1_amd64.deb
sudo dpkg -i libgoocanvas-common_1.0.0-1_all.deb
sudo dpkg -i libgoocanvas3_1.0.0-1_amd64.deb
wget https://launchpad.net/ubuntu/+archive/primary/+files/libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb
sudo dpkg -i libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb
sudo apt-get install -y libextutils-depends-perl libextutils-pkgconfig-perl
sudo dpkg -i libgoo-canvas-perl_0.06-2ubuntu3_amd64.deb
sudo apt-get -f install
{CODE}
Then close shutter, and shutter indicator icon in the task bar, and restart it again. YOu'll be able to edit images again from within shutter.
The first program to try can be -+OpenShot+- (multiplatform).
But if you need more power/features, you can use -+KDEnLive+- (GNU/Linux only, and maybe MacOSX but not Windows).
And if you want to use a newer version than the one that comes with your distribution (either *ubuntu 16.04, 18.04, etc., or even with the Kubuntu-ppa/Backports repo), you can install KDEnLive by means of the -+Flatpack+- system, which works nicely in my first tests {sign user="Xavi" datetime="2018-12-27T12:31:31+00:00"}
{CODE(colors="shell" ln="1")}sudo add-apt-repository ppa:alexlarsson/flatpak

Before exiting the "-+Run console application+-", you need to update (or replace) the customization script in order to make it work with latest Ubuntu versions (16.04+; derived from [https://askubuntu.com/a/699474|here])
Create a file called customize_iso2 in your home directory for instance:

# NAME:
# customize_iso -- customize iso image outside of root FS
#
# SYNOPSIS:
# customize_iso [remaster_home] [customization_scripts_dir]
#
# DESCRIPTION:
# This procedure performs additional customization that needs to
# happen outside of the image of the root file system:
# - Configuration of the boot environment
# - isolinux configuration
# - gfxboot configuration (language/keyboard support!)
# - propagation of a new kernel/initrd
# - Simple bootmanager (directory "install" in image)
# - Configuration of additional resources outside the root FS
# - Add-Ons (like sample document/music/video files)
# - More Add-Ons (like OSS for Win / Mac)
#
# NOTES:
# Execution of the procedure may require Internet access to download
# the source of the latest version gfxboot-theme-ubuntu.
#
# If a local copy of gfxboot-theme-ubuntu is available in the remaster
# home, it will be used instead of a (possibly updated) download.

You can add an extra repository to include -+mkusb dus+- (__Do USB Stuff__), which will allow you to create boot usb disks with persistence of changes in a reliable way for recent Ubuntu distros such as 16.04 LTS and newer. In such distros the default traditional methods such as USB Disk Creator or UnetBootIn no longer work in all cases as they did with earlier Ubuntu versions.

* Get a 16Gb USB disk
* Make two partitions
+ leave 4Mb of free space at the beggining of usb disk
## ~8.5Gb ext4 or ext3
## ~7.5Gb ntfs
* uncompress slax.iso in your linux disk (with -+isomaster+- for instance)
* copy your slax folder to your usb ext4 partition
* run as root the file in your usb ext4 partition: -+sudo bash ./slax/boot/bootinst.sh+- to make your usb bootable
* shutdown your computer, and boot it again this time from your usb stick. Slax should boot
* make your desired changes following guidelines on slax.org website
* change keyboard by hand tweaking a file in the persistent changes folder
** Edit this file -+/root/.fluxbox/startup+- and add there near the top a line such as
++ {CODE()}setxkbmap es
{CODE}* reboot to check that your changes were kept as desired
* clone your usbdisk (with partitions and all) with dd.
** find our your usb disk device name (sdc in my case). you can use command -+sudo lsblk+- or -+sudo fdisk -l+-
** make image with dd. Example:
++ {CODE()}sudo dd if=/dev/sdc of=/media/xavi/mollero_ext4/tmp/backup_slaxomdr.img bs=4M status=progress
{CODE}** clone back over another usb with dd again (or theoretically with a dd GUI, but gdiskdump fails for me on Kubuntu 16.04)
++To restore the image to another USB drive just invert the process. Just make sure that the new USB drive (/dev/sdd in this example) is as big or bigger than the original one

Confirmed that problem still exists on a clean install from Ubuntu 13.04 up to 16.04 on a HP Pavillion dv6 i7. I installed the required program to fix the issue with:
{CODE()}sudo apt-get install ethtool
{CODE}
and we can check the "Wake on lan" current status with:
{CODE(colors="shell")}user@machine:~$ sudo ethtool eth0 | grep Wake-on
[sudo] password for user:
Supports Wake-on: pumbg
Wake-on: g
{CODE}
If under the option ‘Wake-on:’ it says anything other than ‘__d__’ then it means this feature is enabled.
If it’s enabled then on most occasions it’ll say ‘g’ and you can use the below command to disable it.
{CODE(colors="shell")}sudo ethtool -s eth0 wol d
{CODE}
You may not have device __eth0__ but __eno1__ or similar (check using command -+ifconfig+- in the command line)
Then enter the previous command to who the status of ‘Wake-on:’ it should say ‘__d__’.
But the thing is, this setting will be lost as soon as you reboot your computer. So to make Ubuntu permanently save the changes, use the below steps.
{CODE(colors="shell")}gksudo gedit /etc/rc.local
{CODE}
Now simply copy and past the below code into that newly opened configuration file (make sure to paste it above the ‘exit 0’ code).
{CODE(colors="shell")}ethtool -s eth0 wol d
{CODE}
Replace __eth0__ for your own device name if it's different than this (in my case, it's __eno1__).
Since Ubuntu 12.04, you may to do something else. Let’s first copy the original script to the ‘/etc/pm …’ folder, as if we were to edit the file while keeping it on its original location, then it might get overwritten when your OS receives update. So for that, open the terminal window and enter the below command.
{CODE(colors="shell")}sudo cp /usr/lib/pm-utils/power.d/disable_wol /etc/pm/power.d
{CODE}
Now enter the below command to edit it.
{CODE(colors="shell")}gksudo gedit /etc/pm/power.d/disable_wol
{CODE}
Once opened locate a code called ‘wol g’ (you can search for it in the editor) as shown below then simply change the letter ‘g’ to ‘d’.
{img src="https://www.hecticgeek.com/wp-content/uploads/2012/09/Editing-the-disable_wol-script-in-Ubuntu-12.04.jpg"}
Then click on the ‘Save’ button’ and close the editor. Now reboot your PC and when you’ve logged into the desktop use the command -+sudo ethtool eth0 | grep Wake-on+- to know if it’s working or not. If it’s working, then under ‘Wake-on’, now it should say ‘d’ (= disabled).
Open syncthing-gtk UI, and update the syncthing daemon location to -+/usr/bin/syncthing+- if it doesn't get it from there by default, which will be v0.14.16 at the time of this writing {sign user="xavier.depedro" datetime="2016-12-23T08:55:13+00:00"}. {img src="display466" link="display466" width="400" rel="box[g]" imalign="center" desc="Click to expand" align="center" styleimage="border"}Then restart the daemon to get the new and updated binary from the right path, in case you had a previous version of the daemon elsewhere (by default syncthing-gtk downloads a not-so-up-to-date version for you from elsewhere in this path: -+/home/username/.local/bin/syncthing.x64+-)
Otherwise, syncthing-gtk would download an earlier version of the daemon (for instance, v0.14.9 as of the time of this writing {sign user="xavier.depedro" datetime="2016-12-23T08:55:13+00:00"} which is not compatible with the v0.14.14 of the daemon in the sync.evoludata.com or Windows boxes at this time)

With the new systemd configuration, the Unity menu's "hibernate" option does not call on pm-hibernate. It instead uses the hibernate and sleep service of logind / systemd. I'm using a tuxonice kernel, and the tlp power management setup on a thinkpad w520, running Ubuntu 16.04 (devel). I think this article is still relevant even if you don't have tlp or tuxonice, since it's systemd that changes how suspend and hibernate work.
When this laptop suspends or hibernates, sometimes the wifi stops working when it wakes back up. The solution is to unload the wifi device driver module prior to sleep, and then reload it upon resume, the way the "hibernate" script does, and "pm-hibernate" also did.
{CODE(colors="shell")}/etc/systemd/system/wifi-modules-unload-reload.service
{CODE}
{CODE(colors="shell", caption="Contents of the previous file")}# Unload and reload the wifi modules over suspend / resume.

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/sbin/modprobe -r iwldvm
ExecStop=/sbin/modprobe iwldvm
[Install]
WantedBy=sleep.target
{CODE}
The other problem I had was that, using tuxonice, the user ui program was not visible during the hibernation process. I fixed this with:
{CODE(colors="shell")}sudo nano /etc/systemd/system/tuxonice-vtswitch.service
{CODE}
{CODE(colors="shell", caption="Contents of the previous file")}# Switch vt for tuxonice UI

ExecStop=/bin/chvt 7

{CODE}
Enable them with:
{CODE(colors="shell")}sudo systemctl enable wifi-modules-unload-reload.service
sudo systemctl enable tuxonice-vtswitch.service
{CODE}
This worked well in the macbookpro laptop from 2008.
If the previous trick doesn't work (like in a hp laptop with dual graphics card), try this other one:
https://www.youtube.com/watch?v=l8xa-PkDhhk
{CODE()}sudo gedit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash'"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
sudo update-grub
reboot twice!!
{CODE}
However, this didn't work for me. Hibernation or suspending fails in that computer with dual graphics card (ati + intel)
First check if hibernation is compatible with your computer
You should save all of your work before hibernating the computer, just in case something goes wrong and your open applications and documents cannot be recovered when you switch on the computer again.
Run this in a console
{CODE()}sudo pm-hibernate
{CODE}
Enter your password when prompted.
After you computer turns off, switch it back on. Did your open applications re-open?
If hibernate doesn't work, check if your swap partition is at least as large as your available RAM.
If the hibernate test works, you can continue to use the sudo pm-hibernate command when you want to hibernate.
You can also enable the hibernate option in the menus. To do that, use your favorite text editor to create
{CODE()}sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
{CODE}
Add the following to the file and save:
{CODE()}[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
{CODE}
Alternatively, if the previous doesn't work for some reason, you can edit this file:
{CODE()}sudo nano /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla
{CODE}
Search for the sections related to "hibernate", and set __ResultActive=no__ to __ResultActive=yes__
{CODE()}[Disable hibernate by default in upower]
Identity=unix-user:*

ResultActive=yes

By default you can get Adobe Acrobat 8.x in the repositories, as far as I see. But you can download 9.x version in English from Adobe website: http://get.adobe.com/reader/otherversions/
For instance, this version: [http://ardownload.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/AdbeRdr9.5.5-1_i386linux_enu.deb|AdbeRdr9.5.5-1_i386linux_enu.deb]
For 32-bit system:
{CODE()}sudo dpkg -i ~/Downloads/AdbeRdr9.5.5-1_i386linux_enu.deb; sudo apt-get -f install
{CODE}
For 64-bit system:
The easier way to install Adobe Reader DEB on 64 bit Ubuntu is using Gdebi, which will automatically install all dependencies.
{CODE()}sudo dpkg -i --force-architecture AdbeRdr9.5.5-1_i386linux_enu.deb; sudo apt-get -f install
{CODE}
You can Sign PDF documents with PortableSigner, a small Java app that does the job effectively: add the digital signature that can be recognized with Adobe Reader, and it can also place an extra page with a block of text (and you graphical signature as png/jpg in addition if desired) indicating that the document has been digitally signed by a method recognized by Adobe, and you can check the digital signature by means of opening in Adobe Reader the source pdf from that printed document.

Allow runing mod rewrite in Apache
Edit /etc/apache2/sites-enabled/000-default
and change docroot from /var/www to /var/ww/tiki or your custom path, AllowOVerride from None to All, and ensure that the syntax to allow access to override .htaccess file is set with the syntax for Apache 2.4 ("Require all granted") and not with the former one for Apache2.2 ("Order allow,deny" and "Allow from all")
The file should be left as like:

Running Elasticsearch with systemd
To configure Elasticsearch to start automatically when the system boots up, run the following commands:
{CODE(colors="shell")}sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
{CODE}
Info provided in the console standard output:
{QUOTE()}Synchronizing state of elasticsearch.service with SysV init with /lib/systemd/systemd-sysv-install...
Executing /lib/systemd/systemd-sysv-install enable elasticsearch
Created symlink from /etc/systemd/system/multi-user.target.wants/elasticsearch.service to /usr/lib/systemd/system/elasticsearch.service.
{QUOTE}
Elasticsearch can be started and stopped as follows:
{CODE(colors="shell")}sudo systemctl start elasticsearch.service
sudo systemctl stop elasticsearch.service
{CODE}
These commands provide no feedback as to whether Elasticsearch was started successfully or not. Instead, this information will be written in the log files located in /var/log/elasticsearch/.
By default the Elasticsearch service doesn’t log information in the systemd journal. To enable journalctl logging, the ~np~--quiet~/np~ option must be removed from the ExecStart command line in the elasticsearch.service file.
When systemd logging is enabled, the logging information are available using the journalctl commands:
To tail the journal:
{CODE(colors="shell")}sudo journalctl -f
{CODE}To list journal entries for the elasticsearch service:
{CODE(colors="shell")}sudo journalctl --unit elasticsearch
{CODE}To list journal entries for the elasticsearch service starting from a given time:
{CODE(colors="shell")}sudo journalctl --unit elasticsearch --since "2016-10-30 18:17:16"
{CODE}Check man journalctl or https://www.freedesktop.org/software/systemd/man/journalctl.html for more command line options.

Since Freenx doesn't seem to be easily installable in Ubuntu 14.04 servers (at least up to the time of this writing {sign user="Xavi" datetime="2014-10-24T13:01:06+00:00"}). Therefore, we can use an open-source equivalent alternative, called __x2go__ (x2goserver and x2goclient), which is maintained for GNU/Linux based servers, and with supported clients for GNU/Linux, Mac and Windows.
Quick howto to turn your machine into an X2Go server:
{CODE(colors="shell")}sudo apt-get install python-software-properties
sudo apt-add-repository ppa:x2go/stable
sudo apt-get update
sudo apt-get install x2goserver x2goserver-xsession
sudo apt-get install x2gomatebindings # if you use MATE/mubuntu
sudo apt-get install x2golxdebindings # if you use LXDE/lubuntu
{CODE}
You also need to install some desktop environment which is supported by X2Go by default, and in our case, we will install one of the lightest desktops possible: __LXDE__ (see http://wiki.x2go.org/doku.php/doc:de-compat for the full list)
{CODE(colors="shell")}sudo apt-get install -y lxde
{CODE}
__Notes__:
* Remember to install x2goclient in the client computer in order to connect to the server accordingly.
+ {CODE()}sudo apt-get install x2goclient

To write an ISO image file on multiple USB drives simultaneously, you will need the software that is named “MultiWriter”. Ubuntu users will find it in their default repositories with the package name “gnome-multi-writer”.
{CODE(colors="shell")}sudo apt install gnome-multi-writer
{CODE}
(a.k.a. "Multi-boot USB disk")
If you want to write multiple ISO images on one USB in order to have the capacity to boot into a selection of systems by using the same pen drive, you can do it with a tool called “MultiSystem”, or with another one called multiboot.
Add the corresponding repository by entering the following commands on the terminal:
{CODE(colors="shell", ln="1")}sudo add-apt-repository 'deb http://liveusb.info/multisystem/depot all main'
sudo launchpad-getkeys
sudo apt update
sudo apt install multisystem
{CODE}
Open the application and select the device from the list below. Note that the device must be mounted at “/media” and its filesystem must be “FAT32” in order for multisystem to detect it properly.
{REMARKSBOX()}Watch out that it reports that it will write grub boot loader in the Master Boot Record (of the usb? or the main hard disk of your computer??? )
{REMARKSBOX}
MultiSystem started

On the first tab of the application’s menu, you may add your image files one by one. Just hit the green arrow button and a file manager window will let you navigate your local files.
Add image file in MultySystem
Next, you may select the “Menus” tab which is basically a Grub configurator. It will allow you to set up the grub.cfg configuration file set the colors and background image of the bootloader and compile the menu list.
Grub Configurator
Other options include the use of non-free components like the PLoP boot manager and the FiraDisk. Moreover, in the “Boot” tab, you may select system-specific boot options, or just test-drive your creation in the QEMU system virtualization tool, or in VirtualBox. This of course, presupposes the existence of either in your system.
Other Bootmanagers
If MultiSystem isn’t working for you, you may also try alternatives like the multibootusb or the YUMI that basically do the same thing. In general, I have found that all of these tools are a little bit underdeveloped and often riddled with bugs, so you should have patience and not give up easily. Having a multisystem USB stick is worth your time and effort.
From: https://itsfoss.com/multiple-linux-one-usb/
Web: http://multibootusb.org/
Deb: https://github.com/mbusb/multibootusb/releases/download/v9.2.0/python3-multibootusb_9.2.0-1_all.deb
The recommended filesystem is FAT32, so make sure to format your USB drive before creating a multi-boot USB stick.
{img src="display547" width=600}
You can select the persistence size by dragging the slider under MultiBootUSB tab. Persistence gives you an option to save changes to the USB drive in runtime. (in theory; will it work since Ubuntu 16.04 doesn't seem to use it by default?)
{img src="display548" width=600}
Next time I boot through the USB, I get the option of choosing either of the distributions.

You can use seceral programs, each one with its pros and cons. A good advice is to use several to combine info to answer your own questions effectively without confusion (if you use wifi repeaters, or different hardware devices, bytes or bits in units, etc)
Console-based programs:
* -+wavemon+-: ncurses based, updated in realtime, showing mac address of the wifi device for instance to which it's connected (useful to distinguish wifi repeater device from wifi source signal device).
* -+speedtest-cli+-: simple yet useful information of upload and download speed (doing tests). You can show bytes or bits as units, and display simple output.
* -+speedometer+-: nice log with bar chart evolution in terminal, but it shows current use, not doing a tgest on its own. You need to run some big upload or download of data to see it reflected in the graph.
* -+vnstat+-: logs network trafic data and has several useful ways to report usages, etc. See: https://humdi.net/vnstat/
* and a few others (see below)

In theory __ktorrent__ (default torrent app in KDE) is able to search torrents, when you enable a special plugin through the "Ktorrent > View > Plugins > Search" option, but it freezes ktorrent in kubuntu 18.04 for me.
However, you can install __qBittorrent__ (available in the repos), which provides an integrated search tools which works out-of-the-box once you follow a few simp0le steps, described here:
https://www.genbeta.com/paso-a-paso/como-usar-qbittorrent-para-buscar-descargar-torrents-tener-que-visitar-ningun-sitio-web
In short, enable to view search options, update search plugins, and start using it.
