[Trisquel-users] Re : Trisquel repository in Debian

[mtlben]

A default installation of Debian only has the main repository in its source  
list, and is a free OS.  Do not manually add the contrib or non-free  
repositories, and you'll be fine.  To make sure you only have main, let us  
see the content of /etc/apt/sources.list and we'll tell you if everything's  
fine.  Also, show us if you have any extra repo in /etc/apt/sources.list.d.

Do not add the Trisquel repositories to your Debian installation, as they are  
incompatible with Debian (Trisquel is Ubuntu-based) and you'll end up with a  
malfunctioning OS.
