[repost/paraphrased from owut thread]
The ASU side is ok, but the imagebuilder containers are not all present so some targets will fail with an error.
FS just shows init and nothing else.
LuCI ASU shows
Error building the firmware image
Server response: init
and says "report this error".
owut says a bunch of stuff ending with
Error: initializing source docker://ghcr.io/openwrt/imagebuilder:ramips-mt7621-v24.10.1: reading manifest ramips-mt7621-v24.10.1 in ghcr.io/openwrt/imagebuilder: manifest unknown
