I was doing this per the installation guide on OpenCPN wiki/manuals.
My first install of OpenCPN on my RPI 400 opened with a black screen and frozen.


Anyone have success in getting OpenCPN running on a RPI 400?

Following the install instructions got the following message:

which is mentioned in the OpenCPN user manual.
My solution was the following:
sudo apt-get install dirmngr
then the normal OpenCPN install commands
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C865EB40
sudo apt-get update
sudo apt-get install opencpn
Installed successfully and using CM93 charts, appears to be working fine.
Dumb question, why does it install in the "Education menu option" ?
FYI, Using a Raspberry Pi CAN hat to connect to the NMEA2000 network to prototype/test the Linux version of the TwoCan plugin using the SocketCan interface.

Has this been changed in the user manual?

What page is it? (Link please?) PM me to become an editor.

Latest OpenPlotter version works also on an RPI 400. OpenCPN is available in the software, among a lot of other options.

I'm trying to install OpenCPN on a Raspberry Pi 4 8G. When executing: sudo apt-key --keyserver keyserver.ubuntu.com --recv-keys C865EB40, this error occurs:
"Executing: /tmp/apt-key-gpghome.fAA8hHdEnd/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys a9f0f02614646393
gpg: keyserver receive failed: Server indicated a failure"
Any idea what the problem might be?
Thanks! Albert

Installing OpenCPN goes as follows:

sudo add-apt-repository ppapencpn/opencpn

It is possible that add-apt ... is not on your system. Then you must install this first:

sudo apt install software-properties-common

then sudo apt update

sudo apt install opencpn

The key is only needed if you have a different OS version.

If you then try to install OpenCPn you get the message about missing key XXXX. This key you have to add to the keyserver.

I was able to install OpenCPN on my Rpi 400 using this guide:
https://opencpn.org/wiki/dokuwiki/do...spberrypi_rpi2


When I run it , I get a window with OpenCPN title, but it is blank except for "SOG and COG" on bottom of window. I have to kill the process as closing the window brings up "The window OpenCP 5.2.4 does not seem to be responding...".


Thoughts?

[verkerkbr]

My advise is use the OpenPlotter version. You get a lot of extra's and it is working with the RPI 400.


OpenPlotter is a Linux version with a lot of extra added. Easy including installing OpenCPN.

I've searched without finding way to solve my problem. I've installed OpenPlotter on RPi 4 but in Instrument Panel plugin i can't see any paths. Nothing but white page with the words "Signal K Instrument Panel version 0.17.1"
I've tried to reinstall all OS, but nothing different happened. Any suggestion? Thanks a lot...

[verkerkbr]

I think that the SignalK server is not installed. Install via the Settings menu in OpenPlottel Signalk server.

Try this first.

Thanks Bram. SignalK is correctly installed via regular way “settings—>install ecc”

[verkerkbr]

Is the SignalK server running ? Try in a browser localhost:3000.

To start the SignaK server running: sudo signalk-server-setup. All options to N and now the SignalK server start when switching on your system.

Thank you

So if you are still having trouble here is how I did it.

Use the large 1.3 GB image from Openplotter/Openmarine in the link below.

https://cloud.openmarine.net/s/sL9doDML7P4CQDo

Download that to your Windows 10 laptop/desktop or whatever. Then extract (unzip) with say 7 Zip

Then use win32diskimager to send it to your SD Card. This assumes you have the SD Card in that little reader/USB mount and is plugged into to one of the USB connections on your computer.

Now after that completes you should be able to just remove the SD Card and plug it into your RPI and it should then bootup on power up.

Sometimes I have to power mine (one of my RPi's anyway) up several times for a bootup

With this method you never have to go to terminal mode.

No Sudo this or sudo that!

But from time to time you will need to update it from terminal mode.

The problem with Win10 is you don't own the software. MS does updates without notice to the user. They do what they want with their system, you may use, and look in it, what you are doing.

Switching this "spyware" off is almost impossible. As soon as you are connected to the internet the update and changes to the system starts.

The terminal option in Linux is a plus. You can change the settings if you like.

I don't think Win10 is the way to go for navigation software. With other Linux systems you can add most of the OpenPlotter add-ons.

My instruction/method above was to just use your Windows 10 (or Windows 7) Computer to get that Openplotter image loaded on the SD Card.

Then after you move it to your Raspberry Pi, you can then boot up your Raspberry Pi and go from there using the Linux OS.

Sorry, wrong thread for a discussion but reading this kind of nonsense! But I have to respond. Who wants to and why do you want to owe the software? It's maintained for you. No more sudo this and sudo that or apt-get update.
And you are lucky that you live without a mobile phone, Android or Apple!

The point about the "No more sudo this and sudo that or apt-get update" was simply for getting the Openplotter image on the SD Card.

After that though, you'd be using the Linux OS on your Raspberry Pi and those commands at least for updates......
