I'm working with Quantum GIS 1.8 Desktop on Ubuntu 11.10. Two days ago the program crashed while I was working with some WMS layers and then it hasn't been working any more. When I open Quantum GIS Desktop the program starts, the logo appears but nothing more happens and then Ubuntu suddenly quit the application.

I have tried several times both to remove Quantum GIS and to reinstall it, but the problem remains.

Could you help me?

    did you try to do $ sudo apt-get purge qgis ? and then re-install? – nickves Sep 14 '12 at 12:55
  • re-installing is the quickest and best method. If you used a Virtual Box you can take snapshots - I use this method a lot when testing. – Mapperz Sep 14 '12 at 13:18
  • The first command ($ sudo apt-get purge qgis) doesn't work. – user8780 Sep 14 '12 at 14:41
  • I have already tried to uninstall and re-install QGIS several times, but this approach doesn't seem to solve the problem. – user8780 Sep 14 '12 at 14:42

You need to remove the dependencies as well. So after

$sudo apt-get remove qgis


$sudo apt-get autoremove

I hope it works.

  • You could solve that by deleting the lock file. rm /var/lib/dpkg/lock – R.K. Sep 14 '12 at 14:34
