Possibly. I upgraded from 10.10 to 11.04 without a hitch and was hopeful that they hat sorted the standard upgrade issues. I personalize my installs so much that I really hate fresh loads, but I'll be doing only that in the future. Maybe I'll stick to long-term releases only.

I reply to that comment after two days, I don't know if you or anyone else will read this.

My rules of upgrade:

1. Keep your home folder in a separate partition.

2. Backup at least your system partition before upgrading using Remastersys [1]. It creates a live CD/DVD from your custom Debian/Ubuntu system.

3. If the upgrade fails, restore the old system or install the new version and copy/adapt your config files from the backup.
