Upgrade Issues (11.10 -> 12.04)

Asked by vavoysh

So, I was upgrading from 11.10 to 12.04, when suddenly the upgrade decided to log me out and then reboot. When I get back to the login screen, my computer will not recognize my keyboard or my mouse.
Does anyone either know:
a) how to get it so that I can log on and complete the upgrade
b) upgrade from a CD [using live CD, the website does not help]
c) just recover the system so that I can actually use my computer?

I've had an issue every single time that I've had to upgrade, usually resulting in a reinstall - it is extremely annoying, and I would rather not reinstall this time.

Try b).
Live medium is useful in worse case scenarios and when realizing backups.
If there is a separate /home reinstall takes 15 min. without upgrade annoyances.

Set BIOS to boot from CD/DVD, insert LiveCD, boot, proceed with preferred options.
All variants explained there.
