This bug also seems to generate "Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at src/basic /time-util.c:55, function now(). Aborting" in various places if you try to boot an existing 20.04 container on bionic with systemd-nspawn.

It seems however glibc isn't expecting an EPERM, causing numerous programs to fail. In particular, running do-release-upgrade to focal in an nspawn container hosted on bionic will break as soon as the new libc has been unpacked. Solution (tested here) is to cherrypick upstream commit https://github.com/systemd/systemd/commit/6ca677106992321326427c89a40e1c9673a499b2 A newer libseccomp is also needed but this is already being worked on, see bug #1876055. It's a pretty trivial fix one the new libseccomp lands, and there is precedent for SRU-ing for a similar issue in bug #1840640. https://patchwork.kernel.org/patch/10756415/ is apparently the upstream kernel patch, which should give a clearer idea of which architectures are likely to be affected - I noticed it on armhf.
