syntax error unknown user puppet

I used apt-get to remove the puppet packages, but I removed the puppet user by hand. Same happened for mediatomb.

After doing this, I kept seeing this error:

Extracting templates from packages: 100%
Preconfiguring packages ...
dpkg: unrecoverable fatal error, aborting:
 syntax error: unknown user 'puppet' in statoverride file
E: Sub-process /usr/bin/dpkg returned an error code (2)

and also

dpkg: unrecoverable fatal error, aborting:
 syntax error: unknown user 'mediatomb' in statoverride file
E: Sub-process /usr/bin/dpkg returned an error code (2)

Here’s how I fixed it after the tips in “HowTo: Ubuntu unknown user in statoverride”:

sudo sed -i '/puppet/d' /var/lib/dpkg/statoverride

and

sudo sed -i '/mediatomb/d' /var/lib/dpkg/statoverride

Backup to yor taste.
