    You might try to upgrade the package before purging it. In some cases, the new package will fix the removal script (dpkg is made so that new packages can fix even the transition scripts of old packages).

    If that doesn't work, have a look at /var/lib/dpkg/info/openqrm.postinst like Kyle suggested, locate the line that fails, comment it out and try to purge again. Repeat until success.

  2. The following worked for me:

    • rm -rf /var/lib/dpkg/info/openqrm.*
    • rm -rf /usr/share/openqrm
    • rm -rf /etc/default/openqrm
    • rm -rf /etc/init.d/openqrm
    • apt-get purge openqrm

  3. Just try to touch the missing file. If this is just one file missing file it could be a great workaround.

    touch /usr/share/openqrm/etc/openqrm-server.conf

    Now try to remove the package with apt-get or aptitude.

  4. Look at /var/lib/dpkg/info/openqrm.postinst and see what it's trying to do

  5. There's a post here about the same kind of error (different package, though). Have you tried dpkg --force-all yet?
