Description dpw818 2023-12-23 06:21:41 UTC
I had a similar issue in Bug 2251508, and this was fixed after an update.  However, after a system update this evening, I am getting SELinux errors again.  Fortunately this time the suggested policy works as a workaround, which it hadn't before.

Below is the SELinux Alert:

--------

SELinux is preventing systemd-sleep from setattr access on the file /sys/firmware/efi/efivars/HibernateLocation-8cf2644b-4b0b-428f-9387-6d876050dc67.

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

If you believe that systemd-sleep should be allowed setattr access on the HibernateLocation-8cf2644b-4b0b-428f-9387-6d876050dc67 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 'systemd-sleep' --raw | audit2allow -M my-systemdsleep
# semodule -X 300 -i my-systemdsleep.pp
