Next karmic gdm upgrade WILL BREAK your system

[Martin Pitt]

Hello Karmic users,

last Wednesday the new gdm 2.26 landed in Karmic and has caused quite
a bunch of regressions and errors. I just uploaded 2.26.1-0ubuntu3
which should fix the nasty ones, the only major one left is the "Does
not support session saving" dialog (https://launchpad.net/bugs/395324),
which I'm going to address next.

One major bug in the first 2.26 packages was that the package scripts
restarted gdm during the upgrade (https://launchpad.net/bugs/395302).
The package scripts got fixed in 2.26.1-0ubuntu3, so that _from this
version on_ further upgrades will go smoothly. Upgrades from 2.20 (i.
e. Jaunty or Karmic Alpha 2) will also work.

But if you upgraded to gdm 2.26 since last Friday, updating your
system under GNOME will kill the upgrade and your session in the
middle of the update again, since there is no way for the fixed gdm
version to override the previous version's prerm script.

Please follow these steps:

 1. Check your gdm version:

      dpkg -l gdm

    If this says "2.20...", you are fine and can ignore this email.

  2. Do

       sudo apt-get update
       apt-cache show gdm|grep Version:|head -n 1

     If the second command says "2.26.1-0ubuntu3", continue;
     otherwise, wait for an hour. The version should be available on
     archive.ubuntu.com at 1600 UTC today, and a bit later on your
     mirror.

  3. Log out from your X session, to get back to the login manager.

  4. Press Control-Alt-F1 to get to a text console, and log in with
     your normal username/password.

  5. Run an upgrade:

       sudo apt-get dist-upgrade

  6. Press Ctrl+Alt+F7 to get back to the graphical login manager.

Thank you and sorry for the inconvenience,

Martin
