The ansible module which appears to be meant to manage lxc containers is inoperable, and refers to the archived lxc/python2-lxc library.
lxc_container is in the latest ansible-galaxy community.general documentation, but is missing - probably because it cannot be built. Which is pretty disappointing.
The vagrant infrastructure for the lxc provider is a bit creaky too. Seems to work, but there are no official Ubuntu 20.04 LTS boxes.
Is it me, or the ecosystem, that is missing something?
