Comment 42 for bug 811441

I may be a newbie here, but I'm getting Certified in Network+ and Linux+ very soon, and as far as I'm concerned 11.4 is a stable version.

Under windows, I'm usually the type to update all the time, unless the update fails and in which case under windows, you can just system restore if something goes wrong.

Is there anything for Ubuntu like restore for windows?

This upgrade is tricky to install while logged in, so it's probably a better idea to back up files and do a clean install.
