Thats also the reason why the anacron upgrade to Debian 13 gets stuck with root 55481 1 0 08:08 ? 00:00:01 sshd: root@pts/5 root 55488 55481 0 08:08 pts/5 00:00:00 \_ -bash root 56821 55488 0 08:14 pts/5 00:00:02 \_ apt dist-upgrade root 66570 56821 0 08:17 pts/6 00:00:00 \_ /usr/bin/dpkg --status-fd 40 --configure --pending root 66635 66570 0 08:17 pts/6 00:00:00 \_ /bin/sh /var/lib/dpkg/info/anacron.postinst configure 2.3-36 root 66697 66635 0 08:17 pts/6 00:00:00 \_ /usr/bin/perl /usr/bin/deb-systemd-invoke restart anacron.service anacron.timer root 66704 66697 0 08:17 pts/6 00:00:00 \_ systemctl --quiet --system restart anacron.service anacron.timer root 66705 66704 0 08:17 pts/6 00:00:00 \_ /usr/bin/systemd-tty-ask-password-agent --watch
