Comment 1 for bug 1536528

installing the packages before the upgrade fix the problem:

sudo apt-get install libpam-kwallet4 libpam-kwallet5 libdiscovercommon
sudo apt-get dist-upgrade

I will miss muon update notifications :´(
With this update you must choose between muon or muon-discover, muon-updater and muon-notifier. It's no longer possible to install all packages together.

Dependencies should be fixed.
