Bug Description

The desktop cannot add additional languages. The following error pops up:

org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.47'}): org.debian.apt.install-or-remove-packages

It happens each and every time.

To get the error,

LXDE Menu->Preferences->Language Support->Install/Remove Languages (then select a language to try to add)

What should happen instead is that the selected language gets installed. What happens unfortunately is the error message above.

Same system works fine under Unity. The problem seems to be under LXDE.

So it seems.

Are you sure that all files are there that should be present? Is lubuntu-desktop installed?

Also, it might give additional info if you open a terminal window and start Language Support from there (use the command gnome-language-selector).

lubuntu-desktop is installed, version 0.55 Running gnome-language-selector from the terminal gives the same error. Running it as root eliminates the error.

Ok, thanks. Hopefully someone in the Lubuntu team get sight of this bug report soon.

It's the polkit support which have been lost with last update of lxsession. As a temporary solution, you can install lxpolkit, and reboot. That should fix the problem until I make the proper fix.
