I'm running an Ubuntu 16.04 container on Docker.

I exec into the container and run:

apt install apt-show-versions

I get back:

Setting up apt-show-versions (0.22.3) ...
** initializing cache. This may take a while **
Error: No information about packages! (Maybe no deb entries?)
dpkg: error processing package apt-show-versions (--configure):
 subprocess installed post-installation script returned error exit status 255
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

I have no problem installing this package on my host computer also running 16.04.

Anyone know what might be causing the issue?
