EDIT: For anyone encountering this, can be solved with Changes in pi/pi-kernel DTB handling
I’m having the same issue on my device rpi with core18 based on pi-gadget, albeit when installing it on an existing device.
I can’t update the pi-kernel due to
Update assets from kernel "pi-kernel" (357)
2021-10-28T16:55:59+02:00 ERROR gadget does not consume any of the kernel assets needing synced update "dtbs"
And I can’t update the gadget due to
