package cantor 4:16.04.3-0ubuntu1 failed to install/upgrade: Versuch, »/etc/xdg/cantor_lua.knsrc« zu überschreiben, welches auch in Paket cantor-backend-lua 4:16.04.3-0ubuntu1 ist

[Marcus]

Problem occured after failed upgrade from 16.04 to 16.10 (it crashed and I could only login via terminal - repaired the install there with apt-get and --fix-broken option and later (after upgrade and dist-upgrade still failed to make the GUI-login work) I had to change rights for three directories in my home-folder (one of them was ".gnupg" and one ".rpmdb") from root to me (user and group).

So these problems may still stem from the failed upgrade and I try to solve them via purge and reinstall of the cantor package.

But maybe this helps anyone out there (maybe it caused the problems when upgrading?). ;-)
Regards
