Aha! I can reproduce this too. On the machines where this happens, I believe I answered "yes" to a debconf question about restarting services automatically (one of the times I upgraded by hand and not using unattended-upgrades). Maybe something like this would work as a workaround? echo "libc6 libraries/restart-without-asking boolean false" | debconf-set-selections Thanks a lot.
