Linux failed install of OpenCPN

I have installed and run OpenCPN in Elementary OS Loki. I have just installed version 5.0 and cannot install OpenCPN. Elementary 5.0 is based on Ubuntu 18.04 Bionic Beaver but every PPA that I can find for bionic fails to install using gdebi with the error message "Dependancy is not satisfiable opencpn tc data."
TC data cannot be installed without OpenCPN being installed first! Catch22.
Has anyone found a PPA that will install on Elementary 5.0?


Elementary OS 5.0 allows .deb files to be installed by gdebi without all the jumpin through hoops to enable PPAs to be used that was entailed with version 4.0, Its just a pity that no OpenCPN PPA that I can find seems to work.


Who on earth don't the Open CPN developers put the program on to Flatpak https://flatpak.org/ so that it can be installed from there onto almost any Linux PC?

gdebi lets you install local deb packages resolving and installing its dependencies. apt does the same, but only for remote (http, ftp) located packages. It can also resolve build-depends of debian/control files.
It seems to me that you are not using the PPA:s the way they are intended.
See link in the previous post.
If you want to use gdebi to install OpenCPN both OpenCPN and all dependencies including tcdata must be available on your computer.
It is much easier in the long run to set up a ppa correctly, once,...and then forget it ....

Regarding Flatpack. There is pull request from a developer, for using Flatpack.
See this link https://github.com/OpenCPN/OpenCPN/pull/1115
The bottom-line is that Flatpack will probably make it into the next stable version of OpenCPN 5.x.x

Re: Linux failed install of OpenCPN

It is now installed. Thanks to both contributors. It looks as if I left out a character, probably one of the - in my first attempts, so I did it this time by copy and paste of the correct commands. Usefully in its latest version Terminal allows you to paste commands.
