I did some poking around in the apt script (in etc/cron.daily). Here is the output with debug mode on. (I cleared out the time stamp files to force it to update now so errors regarding those are not important.) power status (255) undetermined, continuing system is on main power. sleeping for 739 seconds check_stamp: missing time stamp file: /var/lib/apt/periodic/update-stamp. apt-key net-update (success) download updated metadata (success). send dbus signal (success) X11 connection rejected because of wrong authentication. check_stamp: missing time stamp file: /var/lib/apt/periodic/download-upgradeable-stamp. download upgradable (success) check_stamp: missing time stamp file: /var/lib/apt/periodic/upgrade-stamp. Segmentation fault unattended-upgrade (error) check_stamp: missing time stamp file: /var/lib/apt/periodic/autoclean-stamp. autoclean (success). aged: ctime <30 and mtime <30 and ctime>2 and mtime>2 end remove by archive size: size=412396 < 512000 So, what's that seg fault in the middle there? Turns out it is the call to /usr/bin/unattended-upgrade. I can actually reproduce it like this: $ sudo unattended-upgrade Segmentation fault Now, this is about all I know how to do to debug the issue. If you'd like me to run a stack trace or something on unattended-upgrade to figure out why it is crashing, please point me towards some directions to do so. (I notice that it is a python script and I am not very familiar with python.) In any case, this is a security issue, since security updates cannot be installed automatically, I have to remember to check the server often to make sure that security updates are applied.
