This is pretty weird and I'm wondering if this is an apt bug rather than a lxd packaging bug...
I tried to reproduce your environment here by installing the packages that were conflicting on your system, then doing the LXD upgrade from stock xenial over to backports: ``` root@backports:~# dpkg -l | grep juju ii juju 2.3.7-0ubuntu0.16.04.1 all next generation service orchestration system ii juju-2.0 2.3.7-0ubuntu0.16.04.1 amd64 Juju is devops distilled - client ii juju-deployer 0.6.4-0ubuntu1 all Deploy complex stacks of services using Juju ii python-jujuclient 0.50.5-0ubuntu2~16.04 all Python API client for Juju (Python 2) root@backports:~# dpkg -l | grep lxd ii lxd 2.0.11-0ubuntu1~16.04.4 amd64 Container hypervisor based on LXC - daemon ii lxd-client 2.0.11-0ubuntu1~16.04.4 amd64 Container hypervisor based on LXC - client root@backports:~# apt install -t xenial-backports lxd lxd-client Reading package lists...

Could you maybe try something like this: apt install -t xenial-backports lxd lxd-client liblxc1 lxcfs liblxc-common I wonder if that'll make APT realize that it can totally solve that upgrade by just pulling in the bits that LXD needs and that those do satisfy the dependencies of the existing packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1783225 Title: lxd-client from xenial-backports won't upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1783225/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
