I also encountered the same problem a couple of times — the latest one was:

• https://github.com/sigprof/nur-packages/actions/runs/16077258998/job/45375346786

The problem seems to happen randomly — just rerunning the job without any changes results in a successful run:

• https://github.com/sigprof/nur-packages/actions/runs/16077258998/job/45379167801

Somehow the df -m --output=avail /mnt | tail -n 1 | tr -d ' ' command prints 0 — but I have no idea how that could happen. The runner information which is shown under the “Set up job” step seems to be exactly the same in the broken and successful runs.
