Hi Vasileios,
Here TDE on top of debian stretch

$ /usr/bin/pkexec driver-manager
Cannot run program driver-manager: No such file or directory

Perhaps you can reproduce it while running dbus-monitor --system and tell us
what method exactly causes this error.

Also why using mint when you can use debian native ;-)
