“Nice remote, the Argon1 installation script installed fine on the pukka RPi distribution.
But LibreElec doesn't give you a terminal shell to install them.
SSH would probably work, but you then run into the next problem. Read on!
LibreElec gave a few problems because the installation instructions are outdated/wrong. An updated add-on is available for installation in the LibreElec repository, but it depends on rpi-utilities and system-tools packages which are obsoleted and take a LOT of finding online. Without those, the add-on won't install.
According to the forums, updated scripts are under development, but I have no idea how long before they're available.”
