Comment 12 for bug 966451

It does not effect upgrades via live image. I've never tested using "do-release-upgrade" because I run no server installs.

It does appear running upgrades via "update-manager -d", "update-manager -d -c", and upgrades offered via GUI by the Update Manager/Software Updater when a new version is available.

I'll be glad to perform any additional testing requested, but please be specific about the desired testcase.

BTW I know I'm not Pasi, but with our shortened support cycle for interim releases I truly feel we need to fix any release upgrade bugs ASAP.

I'm not a dev in any stretch of the imagination but I think we need to look to see if xscreensaver or xlockmore are installed prior to beginning the dist-upgrade and then disable both before continuing to prevent confusion.
