Public bug reported:

This issue is exclusively failing on J-5.15 s390x LPAR s2lp4. A manually
provisioned system.

The test will just hang:
$ time sudo python3 ./test-apparmor.py -v ApparmorApport.test_apport_hooks
Running test: './test-apparmor.py' distro: 'Ubuntu 22.04' kernel: '5.15.0-100.110 (Ubuntu 5.15.0-100.110-generic 5.15.143)' arch: 's390x' init: 'systemd' uid: 0/0 SUDO_USER: 'ubuntu')
Skipping private tests

WARN: kernel rate limiting in effect

strace shows the command is trying to read something:
$ sudo strace -p 5993
strace: Process 5993 attached
read(0, ^Cstrace: Process 5993 detached

So if you run the command manually, you will see it's waiting user input
# /usr/bin/python3 /usr/bin/apport-cli apparmor --save /tmp/test
