I have ppa:cr3/ppa in my sources list. It upgrades my checkbox, checkbox-gtk, and checkbox-qt packages to version 0.14~ppa6.12.04. And now I have problems with updating my system, and sometimes critical system errors.

I tried to use ppa-purge to downgrade them - it didn't work. I tried to delete them from synaptic - it wants to delete ubuntu-desktop with them.

When I try to update system I'm getting an error:

 checkbox
 checkbox-gtk
 checkbox-qt
E: Sub-process /usr/bin/dpkg returned an error code (1)

How can I solve this problem?

You should be able to force version for those packages, setting them to use the official repository one doing a click on each of them in synaptic, then package menu -> force version...

Once you set them back, feel free to remove third party repos and upgrade safely.

  • Thank you for your answer. For checkbox-gtk and checkbox-qt it works. But checkbox is remaining 0.14~ppa6 :( I am getting the same error message. – Simplehuman Jun 15 '12 at 09:50
  • checkbox version in official 12.04 repos is 0.13.7. Try forcing it manually with `sudo apt-get install checkbox=0.13.7` – jasmines Jun 15 '12 at 09:58
  • I have purged all of them with ubuntu-desktop package ... And just install them again . Everything is working, thank you. – Simplehuman Jun 15 '12 at 10:26
