Michael, thanks for taking a look. Last time I started
/lib/systemd/systemd-timesyncd directly as root from the command line was
several days ago, way before the today upload of the new versions of systemd
and systemd-timesyncd to stable. Back then, /lib/systemd/systemd-timesyncd did
start, did not print anything and also did not terminate by itself. Hitting
Ctrl+C killed/terminated it, leading me back to the usual bash prompt. Is this
the expected behavior? If this behavior is still the same after the today
upgrade, should I still run strace on the process and post the logs or do
something else? (I'm going to check in a few days because I don't always have
the laptop on which the bug occurs at my disposal.)
(Wild guess: Presumably, during the upgrade from Debian 11 to Debian 12 some
important packages that should be installed in their amd64 versions could have
hypothetically been installed, for whatever reason, in i386. This is something
I observed today on a different machine during an otherwise uneventful, routine
upgrade of dbus. I can try to check via `sudo dpkg -l | awk '/^ii/ && $4 ==
"i386" { print }'`.)
Gratefully,
AlMa
