crazyturk issue is that AMLGX LE12 nightlies are still building with "arm" userspace while the general assumption in our buildsystem is that all ARMv8 SoC devices are now using "aarch64" userspace. In short, the common ARMv8 "arm" repo probably isn't being built and thus does not exist or best case it exists but is incomplete (missing all the binary add-ons) and thus you can't install them. If you look in a Kodi debug log it should be fairly obvious from the URL failures.
I will need to look at bumping kernels to Linux 6.5 and moving AMLGX to aarch64 .. I had been hoping to ignore that for longer.
