After d-u-ing today lightdm did not launch.

Downgrading policykit-1 to testing/unstable resolved this issue.

It did not break here, but I do see some new errors about the session.

hello samoht,

i remember i have seen those message from policikit-1 while dist-upgrading.
Lightdm works fine here™.

Let's assume the two incidents are unrelated.

Does X still start (does text mode login disappear, or do you see a mouse cursor on an empty screen)?
Are you able to login in text mode (perhaps you need to press Ctrl-Alt-F1)? You can run "siduction-irc".

greetings
musca

Thanks to all for helpful comments.
Today I upgraded the packages policykit-1 and lightdm again and all went well.
I suppose the reason for lightdm 's failing launch was not the upgraded package policykit-1.
Greetings
Tom

This moment I did a full d-u, but still policykit-1 complains like cited by samoth in his first posting. No problem starting X though (this is my notebook with systemd running). No autostart here.
