The console output also shows that the hostname job fails on boot, which is abnormal; this job simply calls the 'hostname' command, which is located on the root partition and is a required package. So your system seems to be in an inconsistent state. Please install the debsums tool with 'sudo apt-get install debsums' and post the output of 'debsums -s' from this system.
