Can you tell the relevant steps, thank you @matthiasseemoo

[lzwzzy]

Or do you have the .img file made on rpi3

[TheMMcOfficial]

1) make a backup image if something wrong happen you will have a backup 2) connect to your rpi3 and type: sudo apt update && apt upgrade && apt dist-upgrade the following command will update your system including (apps, kernel ...) 3) reboot

or you can google how to update kernel raspbian (kernel-header)

@lzwzzy Which version of raspbian OS do you use? The same error happened for me before and I found the solution. You have to install raspberrypi-kernel-headers on fresh OS without sudo apt update. This will solve the issue.
