Description of problem:
Opening pictures in Xfce with ristretto triggers this bug everytime.
SELinux is preventing blocking-1 from 'connectto' accesses on the unix_stream_socket /run/systemd/userdb/io.systemd.DynamicUser.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that blocking-1 should be allowed connectto access on the io.systemd.DynamicUser unix_stream_socket by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'blocking-1' --raw | audit2allow -M my-blocking1
# semodule -X 300 -i my-blocking1.pp

Hi,

What process is blocking-1?

Comment 4 hannes 2025-10-21 09:08:23 UTC
I think the source process is bwrap.
SELinux is preventing bwrap from sys_admin access on the cap_userns labeled thumb_t.
