gdm restart failure during libc6 upgrade

[Steve Magoun]

When upgrading my 12.04 system to libc6 2.15-0ubuntu2 via update-manager, I got a debconf prompt that asked me whether services should be restarted. I answered 'yes'. A second or so later I got another debconf dialog that said that gdm failed to restart (see attached screenshot).

Dialog text:
"The following services could not be restarted for the GNU libc library upgrade:
gdm
You will need to start these services manually by running '/etc/init.d/<service> start'."

(Not sure if this should go under gdm since that's where the failure is or libc since that's what triggered the failure)

This bug was fixed in the package eglibc - 2.15-0ubuntu3

---------------
eglibc (2.15-0ubuntu3) precise; urgency=low

  [ Matthias Klose ]
  * debian/debhelper.in/libc.postinst: Call notify-reboot-required for
    updates to 2.15.
  * Expect same test failures on armhf as on armel.
  * Only restart gdm if it is running. LP: #931745.
  * Don't include the non-default multilib debug files in the libc6-dbg
    package on ARM. Install the multiarch package instead.

  [ Steve Langasek ]
  * Synchronize the kernel version checks in
    debian/debhelper.in/libc6.preinst with the values actually set in
    debian/sysdeps/linux.mk.
