I’m currently deploying an estate of 5500 devices running Ubuntu Core 16 in a environment where said devices don’t have internet access.
I need to install core and kernel updates to these devices. I can host my own snap store using https://github.com/noise/snapstore. What I can’t find any information on is how I can put core and kernel updates into that store. Obviously I can get the snaps from my test gateways, but we miss the meta files that presumably the official snap store contains.
I’ve tried manually installing core and kernel updates manually rather than using the store and I haven’t had a lot of luck.
