Description of problem:

Since "dnf --refresh -y update" yesterday morning I'm constantly
bombarded with:

SELinux is preventing rtkit-daemon from sys_ptrace access on the cap_userns labeled rtkit_daemon_t.

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

If you believe that rtkit-daemon should be allowed sys_ptrace access on cap_userns labeled rtkit_daemon_t 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 'rtkit-daemon' --raw | audit2allow -M my-rtkitdaemon
# semodule -X 300 -i my-rtkitdaemon.pp
