I tried: apt remove ca-certificates
and then: apt install ca-certificates But the problem persists.. I'd follow your suggest. I've backed up, some scripts and openbox configurations. Now I'm ready to do a reinstall from scratch. Anyway, before that, I'd like to try to remove all "non-jessie" packages installed, to obtain a "pure" Jessie system. Is there a way with apt or aptitude to achieve that goal?
