My GitHub project uses caches to store download tarballs: https://github.com/spack/spack/blob/develop/.travis.yml#L146,L153
One of these caches got corrupted, and a particular PR could no longer pass its unit tests due to this. When I go to https://travis-ci.org/spack/spack/caches, I see an option to delete the caches for each particular PR, but I don’t see the PR in question. It seems like there is a finite limit on the number of caches displayed, so I need to delete all of the caches before it to see it. However, when I click “Delete all repository caches”, I get a message saying “Oh no! Could not delete the caches”. If I refresh the page, I discover that it actually managed to delete around 20-25 caches, but I have to keep doing this dozens of times to actually clear all caches. Is this a known bug?
