I'am wondering that no mention the latest Flatpak option.
Flatpak is available for 64 bits systems. There is one universal setup working on almost all the
Linux systems.
Flatpak consist of the Flatpak enviroment. A sanbox in which the applications runs.
Can be installed with: sudo apt install flatpak
Then you go to the site: flathub. Search for
OpenCPN and click download.
Next go to Downloads file.
Sudo flatpak install (name of the downloaded file)
Then you get the
OpenCPN flatpak version with all the plugins available. (First do the update of the master plugins in OpenCPN.
Works great and stable.
Not only on my RaspioS, but also on the Ubuntu Yammy for RPI and on my
Linux Mint version on an AMD64.
Not only OpenCPN runs in flatpak, but also a lot of other applications. Here rung Chromium, Libreoffice, VLC Evolution etc. all available in the flatpak format.
You don't need a specific release version any more. But flatpak is only available for a 64 bits OS. RaspiOS64 or Ubuntu Jammy Jellyfish.
