Voleu continuar treballant via SSH? 

Segons sembla, aquesta sessió s'està executant per sota de SSH. 
Actualment no és recomanable realitzar una actualització per sota de 
SSH, atès que en cas de fallada la recuperació és més difícil. 

Si continueu, s'iniciarà un dimoni addicional al port «1022».

S'està iniciant un sshd addicional 

Per facilitar la recuperació en cas de fallada, s'iniciarà un sshd 
addicional al port «1022». Si alguna cosa anés malament amb l'ssh en 
ús, podeu fer servir l'addicional. 
Si feu servir un tallafoc, necessitareu obrir temporalment aquest 
port. Atès que això és potencialment perillós, no es fa 
automàticament. Per exemple, podeu obrir el port amb: 
«iptables -I INPUT -p tcp --dport 1022 -j ACCEPT»
