Description of problem:
SELinux is preventing pool-/usr/libex from 'write' accesses on the directory /var/lib/flatpak/repo/tmp.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow libex to have write access on the tmp directory
Then you need to change the label on /var/lib/flatpak/repo/tmp
Do
# semanage fcontext -a -t FILE_TYPE '/var/lib/flatpak/repo/tmp'
where FILE_TYPE is one of the following: tmpfs_t.
Then execute:
restorecon -v '/var/lib/flatpak/repo/tmp'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that libex should be allowed write access on the tmp directory 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 'pool-/usr/libex' --raw | audit2allow -M my-poolusrlibex
# semodule -X 300 -i my-poolusrlibex.pp
