Lakka doesn't take manual update to nightly

I’m trying to update to the latest nightly from 2.3.2. The system finds the update, extracts it and just reboot in 10s without updating.

Ive had to manually update Lakka by opening it up in my linux distro pc and placing the update file in there.

/LAKKA_DISK/.update

I forgot the reason but they have it listed somewhere in documentation why the update feature was disabled from Lakka.
