Bug#948702: opencpn: Opencpn package is incomplete, adding external plugins is blocked

[Huub Reuver]

Package: opencpn
Version: 5.0.0+dfsg-1
Severity: important

A minimal configuration for opencpn includes at least the following
plugins:
- opencpn-plugin-objsearch
- oesenc-pi
- opencpn-plugin-draw

I need charts, I need to notate and I need to find unknown locations.
Without these opencpn is plainly useless.

Those plugin packages are not available from Debian.
First problem is gshhs dependency (there might be more).
If I use an external repository I find myself pinning out all
debian packages.

Please port the plugins to Debian.

Quick fix:
/etc/apt/preferences.d/opencpn
