Unfortunately, I got into a big mass by trying to upgrade from Ubuntu 10.04.4 to new release 'precise' by running 'do-release-upgrade' to upgrade to it.
Like everyone who tried it, I have stuck at bug
https://bugs.launchpad.net/ubuntu/+s...ts/+bug/990740
So far nothing works.
Is there anyone at this forum or a section of it where I can look for a solution?
