bpo not building packages in staging branch

It looks like the "calculating missing binary packages" job fails for the master_staging_systemd branch: https://builds.sr.ht/~postmarketos/job/1326657

This never completes:

And changed packages in the staging branch are not being built. The systemd branch is currently broken because there's an update to linux-pam, the version in that branch is being replaced by Alpine's version (also see: https://gitlab.com/postmarketOS/pmaports/-/issues/3170).

I do not have access to SSH to failed jobs in builds.sr.ht that run from bpo/postmarketos account, so I wasn't able to get more logs or try to reproduce/debug it
