Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I just ran sudo aptitude update && sudo aptitude dist-upgrade through PuTTY (SSH Client) on my Laptop, which was directed at my fresh Ubuntu server. Unfortunately I just realized I need to be out of the house with my Laptop and I'm worried that by exiting my SSH client or having my Laptop disconnect form the internet that the server won't continue updating!

What will happen if I turn my Laptop off now that the server is updating?!

If it's already past the downloading packages part, don't stop it. If it's still downloading you can hit ctrl-c and stop it then start it again with the suggestions below (it should resume whichever package was downloading) –  DerfK Dec 29 '10 at 23:17

You can do it using

nohup sudo aptitude dist-upgrade &

or (better) using screen, for this one better you study a bit how to use it.

You will be happy then with screen

+1 for screen. A command-line must-have. –  petrus Dec 29 '10 at 23:09
