After applying the suggested updates (179) an error message at the very end of the process suggested me to run apt-get install -f.
Since it is a fairly new Ubuntu install (x86) I didn't setup anything in Thunderbird yet. Different error messages (see details) were generated with the -f process:
~$ sudo apt-get install -f
