Useful extra repositories. You can fire them all in a single go once you have the sudo password in memory (i.e. you have called some command with sudo recently. That's why this list of commands includes some dummy -+sudo ls+- first, so that you type your password if needed, and afterwards, you are not interrupted with the rest of commands that will be executed automagically one after the other if you ciopied the whole list of lines together and pasted them in a terminal window:

Ubuntu 16.04 comes with php 7.0, and some php applications might still fail with php 7.0 .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
sudo add-apt-repository -y ppa:ondrej/php
sudo add-apt-repository -y ppa:ondrej/apache2
sudo apt-get update
sudo apt-get install php5.6 php5.6-mysql php-gettext php5.6-mbstring php-xdebug libapache2-mod-php5.6 php5.6-curl php5.6-gd php5.6-mcrypt php5.6-xml php5.6-xmlrpc libphp5.6-embed php-memcache php5.6-intl php5.6-zip php5.6-sqlite3
sudo install php7.1 php7.1-mysql php-gettext php7.1-mbstring php-xdebug libapache2-mod-php7.1 php7.1-curl php7.1-gd php7.1-mcrypt php7.1-xml php-xml-parser php7.1-xmlrpc libphp7.1-embed php-memcache php7.1-intl php7.1-zip php7.1-sqlite3
{CODE}
Installing both php5.6 & php7.1 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/7.1 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 7.1 you need to do two things:
{CODE(colors="shell")}sudo a2dismod php5.6; sudo a2enmod php7.1; sudo service apache2 restart # For php in web apps
sudo ln -sfn /usr/bin/php7.1 /etc/alternatives/php # For php-cli in the command line
php -v
# PHP 7.0.6-1+donate.sury.org~xenial+1 (cli) ( NTS )
# Copyright (c) 1997-2016 The PHP Group
# Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
# with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
# with Xdebug v2.4.0, Copyright (c) 2002-2016, by Derick Rethans
{CODE}
or from php7.1 to php5.6:
{CODE(colors="shell")}sudo a2dismod php7.1 ; sudo a2enmod php5.6 ; sudo service apache2 restart # For php in web apps
sudo ln -sfn /usr/bin/php5.6 /etc/alternatives/php # For php-cli in the command line
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 php7.1 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__/

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 type="src" src="display466" width="400" desc="Click to expand" rel="box[g]" imalign="center" styleimage="border" align="center"}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]

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

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 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.

^''Coprinus usually gets local IP: 192.168.1.133 from eth0 (and 192.168.1.131 or anoher one from wlan when used instead)''^
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.

From: https://www.howtoforge.com/tutorial/multiple-usb-writing-on-linux/
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
{img src="display550" width=600}
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.
{img src="display549" width=600}
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.

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="2018-12-27T12:32:17+00:00"}

{include page="Video YouTube Playlists"}
You can easily download your own videos of youtube (or even your entire playlsits) through the application -+youtube-dl+- . You can install -+youtube-dl+- from repositories, even if it won't be updated as frequently as needed sometimes, to get sync with youtube way of working. Therefore, you are encouraged to install through the command-line:
{CODE(colors="shell" ln="1" caption="Commands in a terminal window")}sudo apt update && sudo apt install youtube-dl # install programs from repos if you don't have them yet
sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl # get latest version from developers site
sudo chmod a+rx /usr/local/bin/youtube-dl # fix permissions of the downloaded file
sudo youtube-dl -U # update your previous youtube-dl version
{CODE}
You can download your own youtube playlist with:
{CODE(colors="shell" ln="1")}youtube-dl -cit "https://www.youtube.com/playlist?list=YOURPLAYLISTID" -o "%(title)s-%(id)s.%(ext)s"
{CODE}
Replace __YOURPLAYLISTID__ with your own YouTube playlist id (note it's not your youtube channel ID, but the youtube playlist id). You can get it from the url of a video when shown through it's own playlist. That url might look like:
* https://www.youtube.com/watch?v=guFSSJTjyZI&list=__PLM2ch5TKp0OdtMZeqCOJQw6BwJ19VDcj4__&index=2
* https://www.youtube.com/playlist?list=__PLM2ch5TKp0OdtMZeqCOJQw6BwJ19VDcj4__
Therefore, the playlist id is that part after __list=__ and before any ampersand (__&__) if any.
In this case: __PLM2ch5TKp0OdtMZeqCOJQw6BwJ19VDcj4__
Therefore, this would be the instruction in the command line:
{CODE(colors="shell" ln="1")}youtube-dl -cit "https://www.youtube.com/playlist?list=PLM2ch5TKp0OdtMZeqCOJQw6BwJ19VDcj4" -o "%(title)s-%(id)s.%(ext)s"
