hi! this last week systemctl --user stopped working saying:

Failed to connect to bus: No such file or directory

first thing I tried was downgrading systemd but it didn't work. so after reading several pages, I still haven't figured out what's happening but it helped me find several other weird things that I don't know if are related... 1. user@1000.service fails with timeout, is there a way to find what's making the service hang? 2. after restarting user@, polkitd.service says:

Started Authorization Manager. Registered Authentication Agent for unix-process:2622:23390 (system bus name :1.20 [/usr/bin/pkttyagent --notify-fd 4 --fallback], object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) Unregistered Authentication Agent for unix-process:2622:23390 (system bus name :1.20, object path /org/freedesktop/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus)

without registering again which I am not sure if is the correct behaviour but can be due to manually starting user@... 3. and also I've found that XDG_RUNTIME_DIR and XDG_SESSION_ID are not set (neither before or after restarting user@) as should be the case from [1] and [2]. thanks for the help.
