Parts of the CI have been broken here at least since https://github.com/ocurrent/obuilder/commit/12373f18f42fc796638061fdfba31536e25c776f but these failures seem new, and maybe a problem in the infrastructure itself?

Those failures are from flaky tests that have apparently been that way for some time: https://github.com/ocurrent/obuilder/issues/186
