Checked my systems and the way OpenCPN on several systems work. It is the Focal version.

It is probably no problem with de Flatpak OpenCPN 2.6 setup. See info on other item and how to do that setup. Flatpak is a universal Linux application.

Something scrambled in your package manager. Let's try to fix it.
Please do:

$ sudo rm /var/lib/apt/lists/ppa.launchpad.net_opencpn_opencpn_ubuntu_dists_bionic_InRelease

Then, again:

$ sudo apt update
$ sudo apt install opencpn

We'll see how that goes.

rm result:-

rm: cannot remove '/var/lib/apt/lists/ppa.launchpad.net_opencpn_opencpn_ubuntu_dists_bionic_InRelease': No such file or directory

I don't know what that means - but I appreciate all the help!

Well, it is a mystery.
If it were my system, I would burn a new SDCard image, and start over.
But, if you just want to get OCPN installed, do this:


1. In browser, download the following file:
https://launchpad.net/~opencpn/+arch...04.1_armhf.deb


2. $ sudo dpkg -i ~/Downloads/opencpn*.deb


3. $ sudo apt-get install -f

Thanks very much for your persistence! I'll maybe try your second suggestion before resorting to the first. I had just made the [I thought] step forward of getting the Pi4 to boot from an SSD, so I'll give it another chance before starting over.

All the help is much appreciated.

Dave,

The download and install option seems to have worked. Thanks very much for getting me this far!

You are welcome.
I do not really understand what is scrambled in your package management system. Did some research, and most reports suggest that re-installation of the entire OS is really the only way that these things can be reset. Relatively easy on rPI, frightening on a larger system that has been in use for years....


Anyway, good luck with O56.

Dave,
I wonder what will happen with Opencpn when I do ".. update" & ".. upgrade"? Having been installed from the downloaded .deb will it update and upgrade?

I'm not too far along with the Pi4, so restarting from scratch shouldn't be too bad when I get to that point.
Thanks
Dick

Dave,

I just built a usb boot drive from scratch using Raspberry Pi Imager on osx 12.1. I then booted the pi4 with it and allowed the update and upgrade steps that happen on the initial boot up. After rebooting I followed the steps for OpenCPN installation as before, and found a similar outcome. the details are below:-

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 opencpn : Depends: libwxgtk3.0-0v5 (>= 3.0.4+dfsg) but it is not installable

           Recommends: opencpn-sglock-arm32 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Thought I'd let you know about the "start from scratch" option. Not sure whether any of the above will mean anything to you - I'm afraid it doesn't to me.

Best wishes,

Dick

Just checked the os-release - it was "bullseye" - so I changed "bionic" to "focal" and OpenCPN has just installed!

Thanks again for the support in this thread.

Regards

Dick
