The Python 3 unit tests often hang when running in CentOS CI after the test_submit_build_normal test. I am not able to reproduce this locally.
test_submit_build_normal
More investigation is needed to resolve this issue.
PR #1618 is a temporary measure to get CI flowing again. Issue #1617 tracks re-enabling this test.
This issue has been migrated to Fedora Forge: https://forge.fedoraproject.org/koji/mbs/issues/1598
Please continue any further discussion there.
