Description Alejandro 2021-04-14 22:57:00 UTC 
While running the test, the system tries to delete a user, this couldnt happen because the user was still in use, likely a race condition.

We've done 100s of builds since this was last seen in May so closing.

Comment 6 Luca Ceresoli 2022-10-06 20:25:19 UTC 
Probably a race condition in rpm.RpmBasicTest.test_rpm_query_nonroot.

unset_up_test_user() waits up to 30 seconds to "ensure no test1 process in running", then it fails with this error.
Comment 7 Randy MacLeod 2022-10-13 14:46:41 UTC 
Also on master.
Comment 8 Randy MacLeod 2022-10-20 14:59:14 UTC 
backports dunfell and kirkstone
Comment 9 Randy MacLeod 2022-11-10 15:44:40 UTC 
Pavel, are you able to work on this bug or should I move it to unassigned?

Hi Randy,

I'm able to work on this bug. Need few days to sort few things out
Comment 11 Pavel Zhukov 2022-11-13 11:25:33 UTC 
Looks like we hit this: https://github.com/systemd/systemd/issues/8598
Comment 12 Pavel Zhukov 2022-11-13 11:32:31 UTC 
There are few options atm:
- Increase timeout (30 secs currently)
- # systemctl mask user@.service - I'm not sure that will be consequences of disabling user services on project level
- force removal of the user (with "-f" option) 
- Wait for systemd bug to be closed (or fix it :) )
Comment 14 Pavel Zhukov 2023-01-12 12:59:19 UTC 
Hopefully "fixed". Feel free to reopen if happens again
