It seemed that by freak behaviour of systemd my /var/run shm partition was 100% full.. the /var/run/systemd/sessions folder was 1.2Gb and filled /var/run to 100%

after a reboot all was ok

I don't really know what we can do about failed upgrades when /run is full, this part is pretty much a "wont fix". The thing worth looking at is why you have so many user sessions running. Can you reproduce this? In a case where you have that many, please copy&paste the output of "systemd-cgls", "loginctl", and "loginctl show-session XX" for a few XX values of the output of "loginctl", i. e. session names like "c2" or "35". Thanks!
