If I have a broken upgrade, is there a way to re-run the upgrade again?
I had 12.04 LTS installed in a dual boot setup.
I wanted to upgrade to 14.04 LTS (primarily in the hope of solving a problem where sound suddenly stopped working).
I ran do-release-upgrade and my laptop shutdown in the middle of the process.
I rebooted and ran do-release-upgrade again. It finished with errors and booted into command line mode.
After trying to reinstall ubuntu-desktop, the desktop comes up but all the window decorations are black.
If I bring up a terminal it is black on black which is useless.
(I should know at this stage of my life never to do an upgrade :-)).
Update: When running from the Live USB (or whatever) I noticed that I had inadvertently upgraded to 14.10, which is not what I intended. I suspect I will just need to bit the bullet and reinstall.
Update: I deleted the old partitions and just reinstalled. (Unfortunately, the first thing I clicked on "Amazon" seg faulted. Doesn't bode well.)
