This page: libreelec_usb-sd_creator [LibreELEC] shows links to downloading the Creator Tool. I have done that for my Ubuntu 16.04 (64bit) 'puter. Next I ran
chmod +x to the file in ~/Downloads
after that, I ran
sudo ./LibreELEC.USB-SD.Creator.Linux-64bit.bin
The terminal hangs. No Creator launches.
What did I do wrong?
