Public bug reported:
After upgrading an LXD guest machine from 22.04 to 24.04.1, system isn't
healthy, systemctl complains that systemd-binfmt.service fails:
Aug 31 19:23:51 install systemd-binfmt[1147]: Failed to flush binfmt_misc
rules, ignoring: Permission denied
Aug 31 19:23:51 install systemd-binfmt[1147]:
/usr/lib/binfmt.d/python3.12.conf:1: Failed to delete rule 'python3.12',
ignoring: Permission denied
Aug 31 19:23:51 install systemd-binfmt[1147]:
/usr/lib/binfmt.d/python3.12.conf:1: Failed to add binary format 'python3.12':
Permission denied
Aug 31 19:23:51 install systemd[1]: systemd-binfmt.service: Main process
exited, code=exited, status=1/FAILURE
Aug 31 19:23:51 install systemd[1]: systemd-binfmt.service: Failed with result
'exit-code'.
Aug 31 19:23:51 install systemd[1]: Failed to start systemd-binfmt.service -
Set Up Additional Binary Formats.
Reason:
# strace -s 80 /usr/lib/systemd/systemd-binfmt |& fgrep EACCES
openat(AT_FDCWD, "/proc/sys/fs/binfmt_misc/status",
O_WRONLY|O_NOCTTY|O_CLOEXEC) = -1 EACCES (Permission denied)
openat(AT_FDCWD, "/proc/sys/fs/binfmt_misc/python3.12",
O_WRONLY|O_NOCTTY|O_CLOEXEC) = -1 EACCES (Permission denied)
openat(AT_FDCWD, "/proc/sys/fs/binfmt_misc/register",
O_WRONLY|O_NOCTTY|O_CLOEXEC) = -1 EACCES (Permission denied)
There is (like with other programs) a problem with latest LXD/24.04/apparmor
settings. podman/docker also don't run without workarounds in apparmor.
