I started an upgrade, from 11.10 to 12.04, yesterday. I had a couple of power outages, shut down, started up and told ubuntu to go on with "partial" update. I did this twice, and it seemed to keep going, trying to download all 1900-ish files. I had to go out a few hundred files from the end of the "get packages" bit.
When I came back, hours later, the power was out. I don't know if installation finished. Downloading of files may have completed. I don't know if it needs user input at that point.
When I turn on the system now I can't get to the startup screen.
If I choose Ubuntu 3.0.0-17-generic I get a blank screen.
If I choose Ubuntu 3.0.0-17-generic (recovery mode) I go to a menu with various options. But it is screwed. If I press the down arrow it sometimes goes to the option below, other times nothing happens, other times I go to a screen with Ubuntu 11.10 and a light sequence under it (like it is loading, but never gets anywhere).
Sometimes I can select the options.
I can't start the internet from that option.
The command prompt won't display what I type, and sometimes deletes characters. e.g. I type df<carriage return> but it takes f<carriage return>. I managed to df and found that the SSD I boot from is there, as is an external storage HDD, but not the old /home 1TB drive.
sudo apt-get update (when I managed to get that to run) says failed to resolve archive.ubuntu.com.
BTW, when I try to run older versions of Linux, from the grub menu, I have the same problems.
What should I do? I am at work now. Should I download 12.04 onto a memory stick, boot that and upgrade from there again? Will I lose anything?
