Install a package that you've already downloaded :
dpkg -i package.deb
Unpack it :
dpkg --unpack package.deb
dpkg --configure package.deb
A common error is the files collision. When a package contains an installed file, dpkg will refuse to install it.
In this case, if you think this file does not put your system at risk (which is almost always the case), you can force the installation with --force-overwrite.
dpkg -r package.deb
This removal is not complete, every configuration files, scripts, logs and user data will remain. The goal is to keep the possibility of reinstalling it without losing the configuration and all. To completely purge everything use :
dpkg -P package.deb
The equivalent with apt-get :
apt-get remove --purge package.deb
