[sepia] Ubuntu builds from today

A change was merged in chacra a couple months ago that didn't get pushed to the chacra nodes until today. This change is resulting in repo creation failure in chacra. The binaries are there but `reprepro` fails to create the repo. See https://github.com/ceph/chacra/pull/267#issuecomment-548170983 I filed https://github.com/ceph/chacra/pull/271 and pushed it to the chacra nodes so repo creation works again. I doubt this is the proper approach here but I needed to get repo creation working again. All the chacra nodes were updated throughout the day so if you have a build that shows as green in shaman/Jenkins but you're seeing 404 errors from APT or there appears to be no repo at a chacra endpoint, the repo will need to be recreated. For example: chacractl repo recreate ceph/wip-luminous_12.2.13_RC1/621946465d82463e8dc9e3a63fec357272e39d04/ubuntu/bionic You can get chacractl credentials by SSHing to a Jenkins slave. They're in /home/jenkins-build/.chacractl. If you don't have access, ping me with the branch name and sha1 and I can recreate it. -- David Galloway Systems Administrator, RDU Ceph Engineering IRC: dgalloway
