Hi, The removal of the mysql.qcow2 image [1] had a flow-on effect noticed first by Paul in [2] that the tools/image_list.sh "sanity" check was not updated, leading to DIB builds failing in a most unhelpful way as it tries to cache the images for CI builds. So while [2] fixes the problem; one complication here is that the caching script [3] loops through the open devstack branches and tries to collect the images to cache. Now it seems we hadn't closed the liberty or mitaka branches. This causes a problem, because the old branches refer to the old image, but we can't actually commit a fix to change them because the branch is broken (such as [4]). I have taken the liberty of EOL-ing stable/liberty and stable/mitaka for devstack. I get the feeling it was just forgotten at the time. Comments in [4] support this theory. I have also taken the liberty of approving backports of the fix to newton and ocata branches [5],[6]. A few 3rd-party CI people using dib have noticed this failure. As the trio of [4],[5],[6] move through, your builds should start working again.
