apt-get install: unknown user `amavis-stats'

[Simon <greminn@gmail.com>]

Hi There,

I am trying to install spamassassin from sarge-backports with this command:

apt-get install spamassassin/sarge-backports

But im getting this error once the packages have downloaded:

dpkg: syntax error: unknown user `amavis-stats' in statusoverride file
E: Sub-process /usr/bin/dpkg returned an error code (2)

Is there a command to clear this or something? Thanks

Simon
