I built 64 bit ubuntu 16.04 and 14.04 (using crush tunables legacy) systems, and I tried to build a 32 bit system, and it complained about missing packages so if there is such a thing, I think it might be related to 32 bit repository. ubuntu 15.04 doesn't work either, but I'm not sure if it is supported. adminhost$ ceph-deploy install --release luminous vm143 [vm143][DEBUG ] Get:2 http://us.archive.ubuntu.com/ubuntu xenial-updates InRelease [102 kB] [vm143][DEBUG ] Get:3 http://security.ubuntu.com/ubuntu xenial-security InRelease [102 kB] [vm143][DEBUG ] Get:4 http://us.archive.ubuntu.com/ubuntu xenial-backports InRelease [102 kB] [vm143][DEBUG ] Hit:5 https://download.ceph.com/debian-luminous xenial InRelease [vm143][DEBUG ] Fetched 306 kB in 1s (172 kB/s) [vm143][DEBUG ] Reading package lists...
