I have just encountered this issue on an Ubuntu 14.04 LTS instance. It was setup in early 2014, and has had only a light workload serving an API backend for a medical education system in use by many doctors.
Ironically, it seems to be _because_ I enabled unattended-upgrades that the system now cannot update itself. And I not sure how to repair this situation without interrupting service, since many package management commands depend on first doing apt-get update, which is what I cannot do. And I don't think I understand the system well enough to be sure that if I erase something manually it is not critical. If anyone has advice on this, I'd appreciate, even if only pointers to books on more esoteric aspects of Ubuntu package management. $ lsb_release -a No LSB modules are available.
