Hi,
can you please open an upstream report at https://github.com/zhuyaliang/user-admin/issues ?
I do not have an system with only a root account, in result i can't confirm your issue.

Comment 15 Patrick Monnerat 2025-12-03 10:18:46 UTC
> can you please open an upstream report ...

Done: https://github.com/zhuyaliang/user-admin/issues/64

Comment 16 Wolfgang Ulbrich 2026-05-04 15:12:06 UTC
Hi Patrick,
any chance to test https://github.com/zhuyaliang/user-admin/commit/7016ec17eb28ff78024da5408fad64a6261e4707 ?
I am happy to add it to spec file if it fixes the issue.

Comment 17 Patrick Monnerat 2026-05-05 07:51:32 UTC
I was rather waiting for an rpm in updates-testing as I have no dev env on the 0-users vm.

Comment 18 Wolfgang Ulbrich 2026-05-05 11:12:31 UTC
Scratch build for testing https://koji.fedoraproject.org/koji/taskinfo?taskID=145155639
Note, i added some more commits from user-admin master branch. https://github.com/zhuyaliang/user-admin/commits/master/

Comment 19 Patrick Monnerat 2026-05-05 12:37:01 UTC
Thanks for the scratch build.
Tested successfully on a 0-user system:
- Does not crash anymore. The 0-user warning popup still appears, though.
- The lock button and its tooltip are not very clear (no real indication if the lock is active or not). But that's another problem out of the current scope.

The bug is fixed. Thanks.
Patrick

Comment 20 Wolfgang Ulbrich 2026-05-05 14:28:35 UTC
You should send your observations to upstream bugreport. New build coming soon.
