Help setting up OpenPlotter 4

[Kukel]

Hi all,

I have been using a Raspberry Pi with OpenPlotter 3 for a few years. At the beginning of my new sailing season (a few days ago) I did an update. Unfortunately, that broke SignalK and also a few other things. I thought ths would be a good occasion to start anew and switch to OpenPlotter 4, so I flashed the OP4 image to an SD card. Then I updated with sudo apt update, sudo apt upgrade. 

After this, the new card wouldn't boot anymore with the green LED flashing 7 times (kernel.img not found). I repeated the whole process. but with the same outcome. i don't see anything strange in config.txt, also I don't see missing files in /boot/firmware (but I'm not an expert).

Can anyone point me in the right direction? I have no working image now, which is not ideal. 
Thanks in advance.

What Pi & what size sd card are you using?

Yes I downloaded from there. I used the headless image as well.
