Re: [Trisquel-users] debian mark and unmark non free repositories
vrms is the tool for the job in Debian. It goes through all your packages and checks where they came from; if they came from a "contrib", "non-free", "restricted", or "multiverse" section, it lists them appropriately.
Re: [Trisquel-users] debian mark and unmark non free repositories
To my limited understanding, a repo is nothing but a server. Unmarking it should only remove access to it, not to what you installed from it.
Re: [Trisquel-users] debian mark and unmark non free repositories
You'll need to remove the non-free software installed. vrms would be useful for that purpose. https://packages.debian.org/jessie/vrms
[Trisquel-users] debian mark and unmark non free repositories
In debian 8 64bit if you mark non free repositories and install non free software. If you unmark the non free repositories does the system get free software? Or you have to uninstall non free software one by one? Thank you. https://screenshots.debian.net/package/software-properties-gtk
