Tip: Download, unzip and burn on a blank SD card using Balena Etcher
If you have a Themis machine, checkout how to replace the SD
If you don’t have a Themis machine, insert the SD in a raspberry PI3 (or 4), connect to your box and boot, that’s all…
Assuming the raspberry is attributed the address 192.168.1.37 :
- to access to Themis, browse
http://192.168.1.37 - to access to NodeRED (if preinstalled on the image), browse
https://192.168.1.37:1880
Note: these are big files, so be patient :-)
Use xz to extract :
xz -d -v file_name.img.xz
Run sudo apt install xz-utils to install xz on debian/ubuntu
