Can't reach headless machine via ssh or xdrp anymore after yesterday's sync and reboot. Docker services on that machine are up and reachable via web UI, though. Will need to connect monitor and keyboard to see what's going on.
Edit:
Apparently, systemd preset policies have been re-applied with the update. Default policies are to disable these services. To prevent that from happening again, I have now created a custom preset policy file to enable them by default. Learned something new :-)
No hickups otherwise. Happy to be on this distro for years now. Thanks a bunch for all your work :-)
