Summary

Recently we are getting a lot of errors like this in CI:

TypeError: fetch failed

Cause:
SocketError: other side closed

https://woodpecker.join-lemmy.org/repos/129/pipeline/4737/21#L327

This seems entirely random, the same commit can pass CI one time and then fail with this error another time. We need to find a way to fix this, so that CI status can actually be trusted.
