Hi ddg search took me here: https://bugs.debian.org/cgi-bin/bugreport.cgi?att=0;bug=769370;msg=29 which took me to 'man systemd.directives' which took me to 'man 8 pam_systemd' which explains XDG_RUNTIME_DIR Then I tried to look for the name of the package that your system might be missing ... $ locate pam_systemd.so /usr/lib/x86_64-linux-gnu/security/pam_systemd.so $ ll /usr/lib/x86_64-linux-gnu/security/pam_systemd.so -rw-r--r-- 1 root root 455392 2022-03-21 06:55 /usr/lib/x86_64-linux-gnu/security/pam_systemd.so $ dpkg -S /usr/lib/x86_64-linux-gnu/security/pam_systemd.so dpkg-query: no path found matching pattern /usr/lib/x86_64-linux-gnu/security/pam_systemd.so I don't know why that fails. So I tried this: $ dpkg -l | grep 'pam.*systemd' ii libpam-systemd:amd64 247.3-7 amd64 system and service manager - PAM module Maybe you need the libpam-systemd package. Maybe someone else will add to my answer.
