@anarchetic could you update the description with the SRU template: https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template
and in particular having a clearly documented reproducer in the [test case] section will help. thanks! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1883447 Title: nspawn on some 32-bit archs blocks _time64 syscalls, breaks upgrade to focal in containers Status in systemd package in Ubuntu: Fix Released Status in systemd source package in Bionic: New Status in systemd source package in Focal: Fix Released Bug description: Recent Linux kernels introduced a number of new syscalls ending in _time64 to fix Y2038 problem; it appears recent glibc, including the version in focal, test for the existence of these. systemd-nspawn in bionic (237-3ubuntu10.38) doesn't know about these so blocks them by default. 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.
