Why do I have a gezakovacs' PPA?
When I do an update I get this output:
Hit:1 http://ppa.launchpad.net/gezakovacs/ppa/ubuntu xenial InRelease
Hit:2 https://mirror.fsf.org/trisquel flidas InRelease
Hit:3 https://mirror.fsf.org/trisquel flidas-security InRelease
Hit:4 https://mirror.fsf.org/trisquel flidas-updates InRelease

All packages are up to date.
I wonder why is that first PPA on my system, I've never added it. I also want to say that I can't delete it with ppa-purge.
Someone could explain?
