Thanks for filing this bug in ubuntu. It's unclear why this error happened. May I suggest you run the following to see if that fixes it:
sudo apt-get update sudo apt-get -f install You could also try to reinstall the libmspack package: sudo apt-get install --reinstall libmspack0:i386 I just deployed a fresh xenial container, which btw already had libmspack0 installed, but for the amd64 arch. I then added i386, and installed libmspack0:i386, and that worked flawlessly: root@x1:~# dpkg --add-architecture i386 root@x1:~# apt-get update (...) root@x1:~# apt-get install libmspack0:i386 Reading package lists...
