error running apt-get

Hello, When i ran the following code in Ubuntu 16.04,

user@ubuntu:~$ sudo apt-get remove gcc-arm-none-eabi

i am getting the following error message,

[sudo] password for user:

dpkg: error processing package libcrack2:amd64 (--configure):
 package is in a very bad inconsistent state; you should
 reinstall it before attempting configuration
dpkg: dependency problems prevent configuration of cracklib-runtime:
 cracklib-runtime depends on libcrack2 (>= 2.9.2-1ubuntu1); however:
  Package libcrack2:amd64 is not configured yet.

No apport report written because the error message indicates its a followup error from a previous failure.
                          dpkg: error processing package cracklib-runtime (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 libcrack2:amd64
 cracklib-runtime
E: Sub-process /usr/bin/dpkg returned an error code (1)

What has to be done? This is almost the same error every time i try to install any application through terminal.

Kindly help me out in this
