Bug Description

Binary package hint: language-selector

When updating to 0.6.7 from an existing maverick system or when installing from netboot, the upgrade process fails when running postinst.

That happens when no existing language-selector dbus backend is running (quite common).

The issue is:
diff -Nru language-selector-0.6.6/debian/language-selector-common.postinst language-selector-0.6.7/debian/language-selector-common.postinst
--- language-selector-0.6.6/debian/language-selector-common.postinst 2010-10-05 10:14:09.000000000 +0000
+++ language-selector-0.6.7/debian/language-selector-common.postinst 2011-04-19 17:15:45.000000000 +0000

+ # shut down any old language-selector dbus backends
+ kill $(pgrep -U root '^ls-dbus-backend$') 2>/dev/null
  fontconfig-voodoo --auto --quiet || true
     ;;

Where "kill" will return != 0 when the process doesn't exist.

Glad to see this is actively being worked on.

I use cloudinit & cloud-config to bootstrap puppet in EC2, and this bug completely breaks the automatic bootstrap process for new instances.

Even without the fancy cloud-config/puppet stuff, new maverick instances can't be upgraded. If they are, then dpkg is left in a bad state preventing any other packages from being installed.

Thank you for the urgent response to this critical issue.

@Ralph, sure thing (see comment 3). It's been in the -security repository for about 45 minutes now. Sorry for the trouble!
