Hi Annie, I can't confirm that your package is coming from a Canonical or Ubuntu supported archive.
Your log has the following: nova-compute: Installed: (none) Candidate: 2:17.0.4-0ubuntu1~cloud0 Version table: 2:17.0.4-0ubuntu1~cloud0 500 500 http://ubuntu-cloud.archive.canonical.com/ubuntu xenial-proposed/queens/main amd64 Packages 2:13.1.4-0ubuntu4.2 500 500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 2:13.0.0-0ubuntu2 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages Whereas when I add the queens-proposed cloud archive I have: nova-compute: Installed: (none) Candidate: 2:17.0.4-0ubuntu1~cloud0 Version table: 2:17.0.4-0ubuntu1~cloud0 500 500 http://ubuntu-cloud.archive.canonical.com/ubuntu xenial-proposed/queens/main amd64 Packages 2:13.1.4-0ubuntu4.2 500 500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 2:13.0.0-0ubuntu2 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages If you still see problems using the standard Ubuntu archive for xenial with the Queens cloud archive [1] on top of it, please move this bug back to New status.
