For Ubuntu Linux and it's derivatives (Linux Mint) and Debian Jessie based distributions, OpenCPN is distributed from a PPA

Debian
For Debian derivatives, you can use the same packages as for some Ubuntu releases
Debian Oldstable (Wheezy)
You can use the packages from the Ubuntu PPA mentioned above. The compatible Ubuntu Release is Lucid. Unfortunately we can't add new Lucid builds to the PPA anymore due to it being obsolete, so if you need newer plugins, please try to use Precise instead.
There are also monolithic packages containing both the program and basic data, built directly on Wheezy, available from Sourceforge
Debian Stable (Jessie)
You can use the packages from the Ubuntu PPA mentioned above. The compatible Ubuntu Release is Trusty
As wxWidgets 2.8 is now removed from Jessie, you must also add the following apt source: deb ftp://ftp.debian.org/debian/ sid main
