Ceph » devops

We noticed this on our automated test/build system, which is based on Ubuntu Linux 14.04 "trusty". Some time after 5pm CET on 2016-01-06, something must have changed on the DEB repository on http://ceph.com/debian-giant , as our test system started installing the older ceph packages from Ubuntu instead of using the ones from the ceph.com repo.

How to repeat: set up a vanilla Ubuntu 14.04 "trusty" system and add the ceph.com APT repo as outlined in the documentation at http://docs.ceph.com/docs/master/install/get-packages/

The file /etc/apt/sources.list.d/ceph.conf should look as follows:

deb http://download.ceph.com/debian-giant/ trusty main

However, running "apt-get update ; apt-get install ceph" will pick the Ubuntu packages instead:

% sudo apt-get install ceph

Somehow apt decides to choose the Ubuntu packages instead of the ones that should be available from ceph.com.
