I have 2 Xenial systems. They are both fully up-to-date as of 5 minutes ago. The failing system is a laptop running XFCE GUI, and I'm attempting to use LXC from a GUI terminal. The other system is a linode that I access via ssh, and LXC works fine there. I believe I've configured the two systems the same way w.r.t. lxc (e.g. /etc/subuid, /etx/lxc/lxc-usernet, ~/.config/lxc/default.conf, etc.). The primary difference is that the Linode system is running a Linode-provided kernel, whereas my laptop is running an Ubuntu-provided kernel.
