Description of problem:
SELinux is preventing systemd-user-ru from 'unlink' accesses on the lnk_file .flatpak-cache.

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

If you believe that systemd-user-ru should be allowed unlink access on the .flatpak-cache lnk_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-user-ru' --raw | audit2allow -M my-systemduserru
# semodule -X 300 -i my-systemduserru.pp
