Public bug reported:
LXC released 4.0.12 as a bugfix release and is now in jammy. We'd like to line
things up in focal.
The proposed SRU will bump from 4.0.6 all the way to 4.0.12, lining it up with
what's currently in jammy. We've been skipping a few of the bugfix releases in
focal so far, mostly catching up when we're starting to see problems with the
older version.
In this case, we've seen a number of issues when running with the HWE
kernels as well as autopkgtest issues on foreign architectures (arm64
and s390x), all those will go away with this bump as we've confirmed
everything is clean in jammy.

Just like Ubuntu itself, upstream releases long term support releases,
e.g. 4.0, and then periodic point releases including all the accumulated
bugfixes.
Only the latest upstream release gets full support from the upstream
developers, everyone else is expected to first update to it before
receiving any kind of support.
This should qualify under the minor/micro upstream bugfix release
allowance of the SRU policy, letting us SRU this without paperwork for
every single change included in this upstream release.
[Test case]
lxc has autopkgtests which will assert that the binaries built in -proposed are
functional.
