Description Jose U. 2024-04-23 21:03:43 UTC
Description of problem:
SELinux is preventing /usr/sbin/plymouthd from 'read' accesses on the file /sys/firmware/efi/efivars/SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c.

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

If you believe that plymouthd should be allowed read access on the SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c file 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 'plymouthd' --raw | audit2allow -M my-plymouthd
# semodule -X 300 -i my-plymouthd.pp
