The most common error is the installation of panto-default-settings and here is how to fix almost any broken package:
- Open your file manager thunar locate the package panto-default-settings under /var/lib/dpkg/info/ and delete any file has the name starting with panto-default-settings .
- Open synaptic and remove panto-default-settings.
- Locate panto-default-settings with synaptic and reinstall panto-default-settings.
This package has a old version wich needs to be removed,it was broken.
Thank you all for your support all this years!
