Description of problem:
flatpak update
SELinux is preventing flatpak-system- from 'read' accesses on the file /etc/passwd.

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

If you believe that flatpak-system- should be allowed read access on the passwd 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 'flatpak-system-' --raw | audit2allow -M my-flatpaksystem
# semodule -X 300 -i my-flatpaksystem.pp
