I have do it but the answer is:

error: No such ref ‘app/org.opencpn.OpenCPN/arm/stable’ in remote opencpn-origin

What can I do for go in opencpn install ?

I have installed the Raspi OS Legacy 64 bit on my Pi4
Also installed gpsd to control my gps connected in USB.
Version installed:

pi@raspberrypi:~/Downloads $ uname -a
Linux raspberrypi 5.10.103-v7l+ #1529 SMP Tue Mar 8 12:24:00 GMT 2022 armv7l GNU/Linux

Thank for the help

this is not the 64 bits OS. It should say aarch64 GNU/Linux

Thank you for the answer, But I dont understand what you mean.

Thank for the answer hub , but I don’t unsderstand it, sorry.

You are not running the 64-bit operating system. That’s what uname -a shows.

Thanks You
You right, I suppose that you are a kind of genious to know all those thinks :slightly_smiling_face:
After the correction to use the correct version, All is working like I want.

My last interrogation: how to use Raspi4 in 64 bit version… But I 'll investigate later
Many ,many thank for your quick and efficient answers
