Upgrade experiences from 8.04 LTS to 10.04 LTS?
Solution 1:
I have tested this myself on a VM. And as Andrew said, this was heavily tested before the release.
Solution 2:
Yes, I upgraded a production system, and worked fine.
Solution 3:
While I haven't, that is one thing that gets heavily tested in LTS releases prior to their release.
Solution 4:
I upgraded a production system from 8.04 to 10.04. I had to switch from gdm to kdm because gdm would not find any users to log in (but one could log in through a VT.)
I've filed the bug in Launchpad but it was never even triaged, not even with a request for more info! At least it saved me from having to reinstall the box.
Otherwise no hiccups. I removed Flash and Nvidia binary blobs from the machine (user requested it) before upgrading and then reinstalled them from the packages later. The new nouveau drivers are slick (VTs actually work with nouveau.)
Solution 5:
Done on a VM, using the desktop edition. Seen no issue.
