remove a package entry that has "rc" in the begining on "dpkg -l"

[Siju George]

Hi all,

I understand that the package below is not installed but the
confiruration files remain

# dpkg -l |grep apache
rc  libapache2-mod 4.3.10-16      server-side, HTML-embedded scripting languag

How do I purge the configuration files too and get this package out of
dpkg listing?

Thankyou so much

Kind Regards

Siju
