[Bug 966451] Re: When xscreensaver/xlockmore isn't properly stopped, the upgrade leads to a broken system

[Erick Brunzell]

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.

Title:
  When xscreensaver/xlockmore isn't properly stopped, the upgrade leads
  to a broken system

Status in Software Updater:
  New
Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  During the installation, the following message is shown:

  "Configuring libc6
  xscreensaver and xlockmore must be restarted before upgrading
  One or more running instances of xscreensaver or xlockmore have been detected on this system. Because of incompatible library changes, the upgrade of the GNU libc library will leave you unable to authenticate to these programs. You should arrange for these programs to be restarted or stopped before continuing this upgrade, to avoid locking your users out of their current sessions."

  If you close the window by clicking the close button, the installation
  is broken. However if you click "Continue", the installation proceeds
  normally.

  Affected upgrades include:
  – Lubuntu 11.10 to 12.04 (i386)
  – Lubuntu 12.10 to 13.04 (i386 and amd64)
  – Can be confirmed on Xubuntu upgrades as well

  Preferred solution:
  The installer should be able to stop xscreensaver and xlockmore automatically.
