package language-selector-common 0.6.7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

I just encountered the same error:

"Setting up language-selector-common (0.6.7) ...
dpkg: error processing language-selector-common (--configure):
 subprocess installed post-installation script returned error exit status 2 . . . "

I am encountering the same error as above. This was working about an hour ago. Seems like a new version of the language-selector-common package may have been pushed with a bug?

I have got the same error message auf dist-upgrade:

"...

I confirm that bug on my system also.
The same logs as Katian and others.

Is there any way to recover "by hand" ?

Also got the same problem on my server after running updates, not quite sure what to do about it, tryed "sudo apt-get -f install" and "sudo dpkg --configure --pending" with no luck!

Patch attached. I don't know how to branch and ask for a merge.

Apparently there's a problem on postinst script trying to kill a process that does not exists on all ubuntu.

Yep, I have just commented out that line and it fixes the problem here too.

I can also confirm this bug on Ubuntu 10.10 x64, and that the patch proposed in #11 resolved the issue for me.

A quick 'fix' is to create a script called

ls-dbus-backend

with the following contents:

#!/bin/bash
sleep 900
exit 0

then run as root in one shell:

sudo ./ls-dbus-backend

and run in another shell:

sudo apt-get -f install

How can I use or apply this patch?

I confirm this bug too (Ubuntu 10.10 - 32bit on Asus EeePC 1005PE)

I can confirm the patch in #11 works for me as well.

I can also confirm this bug on Ubuntu 10.10 x64, and that the patch proposed in #11 resolved the issue for me.

I can confirm this bug on Ubuntu 10.10, and also that the quick fix suggestion in comment #14 worked for me.

you can edit the file /var/lib/dpkg/info/language-selector-common.postinst go to the line with this content :
kill $(pgrep -U root '^ls-dbus-backend$') 2>/dev/null
at the end add || true to get this line
kill $(pgrep -U root '^ls-dbus-backend$') 2>/dev/null || true

run apt-get upgrade again

This fix the problem for me

This bug is about to be fixed via bug 766534.

Thank you!

#14 worked for me

It looks like the fix is in the repository now. Apt get update and apt get upgrade. I suspect this can be closed now.

@Gus
This bug report is in effect closed already, since it's marked as a duplicate of the closed bug 766534. ;-)

apt-get update && apt-get updgrade will still fail as of today. It will not let you properly install language-selector-common. I have confirmed that you need to edit a file for post installation:

sudo vi /var/lib/dpkg/info/language-selector-common.postinst

Look for this line:

kill $(pgrep -U root '^ls-dbus-backend$') 2>/dev/null

append || true so that its look like:

kill $(pgrep -U root '^ls-dbus-backend$') 2>/dev/null || true

then run:

 sudo apt-get update && sudo apt-get upgrade

This method will fix the issue, a simple apt-get upgrade will not fix the problems as of yet.

@roachmmflhyr
It seems to me that your comment would fit better on bug 766672, which is still open. Please review that bug report including the comments, and possibly repost your comment there.
