I’ve downloaded JetPack 4.6.1 and flashed to the sdcard using Etcher as per the tutorial instructions, but when I booted for the first time I got the following error message: The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again
It’s all Okay now. Indeed, I went through the headless configuration steps using putty on windows and after completing the installation I restarted with the display attached and everything went fine. Thanks
