You’ve just run ‘mintupgrade upgrade’
During the upgrade process your system start looping endlessly and you see many errors, but a notable one keeps on re-appearing, namely:
dpkg: error processing package gconf2 (–configure):
dependency problems – leaving triggers unprocessed
dpkg: dependency problems prevent processing triggers for gconf2:
gconf2 depends on dbus-x11; however:
Package dbus-x11 is not configured yet.
Solution:
sudo dpkg –configure -a
Now run ‘mintupgrade upgrade’ again.
