Hello, Recently, I noticed that on Ubuntu Xenial 'stud' for tls-proxy option is no longer available and replaced by 'hitch'. I filed a bug report and proposed a fix. https://bugs.launchpad.net/devstack/+bug/1613071 https://review.openstack.org/#/c/355253/ Ian gave me +1, and could anyone else review my fix? BTW, I noticed there are some more issues around devstack keystone support. I'll continue working on them. Best regards, Masanori
