Hi,
lxc currently fails to build against glibc 2.36, which also affects
its autopkgtests. Here's an excerpt of the failed build logs
containing the first error detected:

I believe the following upstream PR should fix the issue:
https://github.com/lxc/lxc/pull/4181
I'll be testing a patched version shortly and will post a debdiff if
it pans out.
