Can't remove, purge, unistall mongodb from debian

I'm trying to reinstall it, because it has problems. For example, I can't install Chromium because mongodb-org-server is not configured. But I can't even remove it for the same reason.

apt-get autoremove --purge mongodb

Or:

apt-get purge mongodb

Or:

apt-get remove --purge mongodb

All end in the same way:

 dpkg: error processing package mongodb-org-server (--configure):
  subprocess installed post-installation script returned error exit status 102
 Errors were encountered while processing:
  mongodb-org-server
 E: Sub-process /usr/bin/dpkg returned an error code (1)

Some data about my machine from hostnamectl:

  Operating System: Debian GNU/Linux 8 (jessie)
  Kernel: Linux 3.14-2-amd64
  Architecture: x86_64

How can I fix this?

To avoid that sort of problems you should install software only from native Debian repositories. Unfortunately it is not unusual when sloppy/incompetent 3rd party packages are responsible for such troubles.

To recover try removing file /var/lib/dpkg/info/mongodb-org-server.postinst before attempting to apt-get purge mongodb.

Remove all mongodb file inside
