wpkg --no-force-distribution | --refuse-distribution ...
The --no-force-distribution option prevents you from installing a package which distribution is not the same as the target installation distribution. For many installations, administrators do not constain a target to a specific distribution.
The --no-force-distribution option ensures that the distribution matching is enforced when defined in the target control file. It can be quite useful to prevent spurious packages from being installed in your target system.
The --refuse-distribution is an exact equivalent.
