Upgrade Error. Now on Half-way between ubuntu 11.10 and 12.04 HELP!
Lost power during upgrade, how do I recover?

I began to upgrade from 11.10 to 12.04, but someone shut down my computer halfway and now it only offers partial upgrade. How can I undo this and restart the upgrade process, or just complete it?

  • @gertvdijk, that one is about losing one's internet connection. From personal experience several times over, I feel the upgrade process is robust enough to handle a disconnect/reconnect. But here is a case of shutting down. – user25656 Feb 1 '13 at 2:40
  • @vasa1 You're right. I must have copy/pasted the wrong question in! I had a few of those similar ones and this was not the one I meant to dupe it with. Brooke: I'm terribly sorry - I'm voting-to reopen. – gertvdijk Feb 1 '13 at 9:43
  • This is still a dupe, and it should still be closed. I've just edited the question to point to the correct duplicate. – Tom Brossman Feb 1 '13 at 10:13
  • @TomBrossman Okay, I thought the "official" steps were to reopen and close with the right duplicate. Anyway, thanks. :) – gertvdijk Feb 1 '13 at 14:21
  • @gertvdijk good point, now asked in meta. – Tom Brossman Feb 2 '13 at 16:27
