Description of problem:
flatpak added:

Requires(post): policycoreutils
Requires(post): policycoreutils-python
Requires(postun): policycoreutils-python

https://src.fedoraproject.org/rpms/flatpak/c/b6456a51bb98ec1bd6b6dbdc5bcc46bad2f1930a?branch=master

policycoreutils-python is ambiguous. flatpak should require one of the following:

python3-policycoreutils if it works with Python 3
python2-policycoreutils if it needs Python 2 (a fesco/fpc exception would be needed)
policycoreutils-python-utils if you need any of:
  /usr/bin/audit2allow
  /usr/bin/audit2why
  /usr/bin/chcat
  /usr/bin/sandbox
  /usr/sbin/semanage

Or, require the thing you need directly.

It seems that the requires were added together with %selinux_modules_install and %selinux_modules_uninstall. Those need:

/etc/selinux/config (selinux-policy)
/usr/sbin/semodule (policycoreutils)
/usr/sbin/selinuxenabled (libselinux-utils)
/usr/sbin/load_policy (policycoreutils)

I don't see why you need policycoreutils-python.
