Repair Ubuntu after unsuccesful upgrading

3

I was upgrading Ubuntu 11.10 to Ubuntu 12.04 and during this process I was using Google Chrome and some Nautilus windows and suddenly something came wrong (compiz or other package was updating...) X server wasn't responding. I had to restart my laptop because upgrading process wasn't going on. Since then Ubuntu doesn't stand up. After grub choise nothing shows (except blinking mouse pointer and purple background). I even can't switch to tty.

Enyone knows solution to that problem? How to repair this installation of Ubuntu. How get access to terminal (to diagnose, to check the system)?

In the years since the XKCD cartoon on the subject, upgrading Ubuntu hasn't gotten much better – William Entriken – 2015-12-24T21:49:44.447

Boot a live system from CD or USB drive and mount your hard drive(s). Then you can fix the system or restore your backup that you were advised to make before a major system upgrade. – Marco – 2012-05-04T15:47:00.627

The exact same thing happened to me just now. Doing the dist-upgrade trick right now. Let's wait and see if that works... – Arne – 2013-05-23T20:14:31.343

In my case, after a crash during 11.10 to 12.04 upgrade, this command completed the upgrade:

sudo apt-get -f dist-upgrade

, as suggested in https://askubuntu.com/a/122320.

About 600M of packages was downloaded and installed in the process.

Try using the Ubuntu LiveCD Recovery Mode. It gives you exactly what you need for repairing the system.
