[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jarno Suni (jarnos)]

I got this when upgrading from 16.04 to 18.04

[Cocodude (marc-indivisibilities)]

Also got this when upgrading from 16.04 to 18.04.

Running "dpkg -r --force-depends libpt2.10.10v5" and then "apt-get -f install" seemed to fix this.
