OCharts incompatibility 5.9.2

[Dockhead]

I experienced a hard drive failure while cruising on my nav computer. I just happened to have a spare SSD drive on board. I swapped this out and installed Ubuntu Linux, which I had been meaning to do anyway.


Ubuntu is a pretty steep learning curve but I managed to get O installed, but the problem I have is that the OCharts plugin is incompatible and crashes O. I find no other version of the Plugin.


I did not choose 5.9.2 -- is that a beta? I thought I installed only the ppapencpn/opencpn which I thought only had stable versions.


Any advice?


If the problem is the OpenCPN version, how do you change that? The method of software installation in Ubuntu is fairly baffling to the new user.

Update:

I managed to remove 5.9.2 and install 5.8.4 but I still have the same problem.

It says the O-Charts plugin is incompatible and will be uninstalled, whereupon O hard crashes.

Maybe there is an alternative download for the right plugin?


Also, I don't see the Logbook plugin, in the plugin catalogue. Does this not exist for the Linux version of O?
