I think I’ve mentioned that before. Either on the mailing list or during one of the online get-togethers. When the RBE is building metadata about the packages and the release in general, it verifies the zip archives. It also, dives through nested zip archives. The RBE does throw non-critical error messages/logs about corrupt zips. There are corrupt zip archives inside some packages. I’m on my phone right now. So, I cannot recall which or how many. Next time I do a test build with the RBE I’ll let you know. If I recall correctly, at least one is a couple zips deep in the OpenGEM sources. > > Thanks!
