Notes
[stretch] - lxc <no-dsa> (Minor issue)
[jessie] - lxc <ignored> (https://lists.debian.org/debian-lts/2020/02/msg00102.html)
LXC 3.0.2 split the templates out to separate lxc-templates.
https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1661447
Some of the templates were switched to fetch the pacakges over HTTPS, cf.
https://github.com/lxc/lxc/pull/1371 for the lxc-fedora template.
No security commitments from upstream and lxc-ltemplates deprecated in favour of
distrobuilder.
