Setting up x11-common (1:7.7+1ubuntu8.1) ...

insserv: warning: script 'mosquitto' missing LSB tags and overrides
insserv: There is a loop between service minidlna and mosquitto if stopped
insserv: loop involving service mosquitto at depth 2
insserv: loop involving service minidlna at depth 1
insserv: Stopping mosquitto depends on minidlna and therefore on system facility `$all' which can not be true!
insserv: exiting now without changing boot order!

E: Sub-process /usr/bin/dpkg returned an error code (1)

Answer 1

insserv: There is a loop between service minidlna and mosquitto if stopped

This is where the problem lies, IMHO. We need to deal with the scripts of these two services, which refer to each other when trying to stop them, which is why all the fuss. Or just delete one of them. Or both.

Answer 2

If the package is not installed or removed, then I know only one solution:
open the /var/lib/dpkg/status file, find the lines about the package and delete them. after which we try the commands again.
