For updating CoreELEC while using the command line interface, you have to
SSH 47 in, using username:
root and password:
coreelec and then move to the correct folder with the command cd /storage/.update
Once at the correct folder, the specific file can be downloaded directly to our device using
wget
https://github.com/CoreELEC/CoreELEC/releases/download/8.90.5/xxxxxx.tar
(substituting
8.90.5 with latest version number and
xxxxxx.tar with the correct file for your device).
If preferred, a previously downloaded update file can, of course, be transferred to the
/storage/.updatefolder, using your favourite SSH software.
Once the update file is in the correct folder, reboot the device
The update process will start after that by unpacking and installing the update, followed by a another reboot.
