In the process of following this guide https://ubuntu.com/core/docs/image-building on building custom Ubuntu Core images I ran into an issue I have not encountered before. I did complete this process fully some time in the past (I believe 2 months ago) and I did successfully flash the image onto an IoT device.
After following the guide step by step I got the following model assertion (here the “cloudlink” snap is a custom snap I manage personally, “id” and “channel” are correct):
After entering the following command:
$ ubuntu-image snap .model
The following error occured:
Error: Error preparing image: cannot override channels, add devmode snaps, local snaps, or extra snaps with a model of grade higher than dangerous
Does anyone know what exactly this error is trying to say and what I can do to fix this issue? Thanks for any help!
