Agent does not seem to try all configured repositories if one of them is offline

[soenkeliebau]

The cluster in question had three repositories configured at the time the behavior was encountered.

localrepo: localhost:8000 - unreachable, as no webserver was running
stackablerepo: repo.stackable.tech - should have been reachable
integration-test-repo: https://raw.githubusercontent.com/stackabletech/integration-test-repo/6d784f1fb433123cb3b1d5cd7364a4553246d749/ -> reachable

Agent logs seem to indicate that it tried the local repo first and then aborted when that failed instead of trying the next repo.
