SELinux is preventing /usr/libexec/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
