cannot install ajenti because of apt-show-versions

[imranity]

im getting this on my docker build when i run docker build -t ajenti . :

** 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
dpkg: dependency problems prevent configuration of ajenti:
 ajenti depends on apt-show-versions; however:
  Package apt-show-versions is not configured yet.

dpkg: error processing package ajenti (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 apt-show-versions
 ajenti
E: Sub-process /usr/bin/dpkg returned an error code (1)

i tried installing apt-show-versions prior to ajenti , but same error of dpkg i get on it...

Solution:
apt-get purge apt-show-versions
rm /var/lib/dpkg/info/apt-show-versions*
rm /etc/apt/apt.conf.d/docker-gzip-indexes
apt-get-update
apt-get install apt-show-versions
apt-show-versions -i
