Following #950533, I also had a problem upgrading systemd in a chroot, where
files in /, /var, /var/log are all owned by sbuild:sbuild. The upgrading script

Why would you make all files owned by sbuild:sbuild?

I'm in the same situation as Andrey, the chroot was created long time ago, probably by a helper script (schroot-setup?). I've no idea why these files are owned by sbuild:sbuild. The entire chroot seems to be owned by sbuild:sbuild.

tried to create a dir /var/log/journal/, owned by root:root, and then failed
without a lot of clues...

Can you run
SYSTEMD_LOG_LEVEL=debug systemd-tmpfiles --create --prefix /var/log/journal
echo $?

please and attach the output

/var/log/journal is root:systemd-journal now.

As I said, I already chowned /var/log/journal to sbuild:sbuild, and then I was able to upgrade. So, it will probably not help a lot, sorry... The logs are in the attached debug.log.
