RPM build workflow failing for github actions

[prestist]

Bug

Environment

Github action

Expected Behavior

RPM build completes successfully after pushing valid changes.

Actual Behavior

Currently when trying to land a PR into Afterburn you see that your RPM build will fail.

RPM build warnings: mv *.src.rpm $outdir munmap_chunk(): invalid pointer /__w/_temp/f0dea351-4870-4fd7-bae0-07d688f3703d.sh: line 3: 362 Aborted (core dumped) mock --rebuild --enablerepo=updates-testing rpms/*.src.rpm

Note: I have been unable to reproduce this locally. this seems to be limited to the github action environment.

Reproduction Steps

1. Create a simple PR and watch the workflows build,
2. Look at the RPM build, and see failure.

Other Information

Looks like this seems to be a bug in usermode, https://pagure.io/usermode/issue/12. Since we cannot devise a working workaround for this we will have to disable the workflow if something must land. For now we will block on this until priority changes.

Maybe we should consider switching to Packit for RPM test builds

Looks like the RPM builds when switching to Ubuntu 22.04 runners: coreos/coreos-installer#1590

We can probably use that as a workaround while we work on switching the RPM test build to Packit.

Would need to be switched in https://github.com/coreos/repo-templates/blob/main/rust/rpm-test.yml

This could be seccomp-related. One test to do is to go back to latest Ubuntu, but add --security-opt=seccomp=unconfined to the podman invocation to see if that helps.

Trying that in coreos/coreos-installer#1592
