I am reopening the Trusty task, as I've re-confirmed this bug in 14.04 chroot. apt upgrading will fail on libpam-systemd:
root@x250:/# apt dist-upgrade Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages were automatically installed and are no longer required: libfreetype6 os-prober Use 'apt-get autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue?
