run this 1 line for it:
cd ~;mkdir .desirecore;cd .desirecore;wget https://github.com/ZonnCash/sentinel/releases/download/v1.1.0-win64/sentinel-lin64 ;chmod +x sentinel-lin64;

Before run, install and run screen:

apt-get instal screen
screen
./sentinel-lin64
You will see it running, so then you can close window. Screen will make it running from behind, so wait around 30min to see ENABLED instead of WATCHDOG EXPIRED.
