I hope you meant snapd/ubuntu-image here :-)

There might be work here for snapcraft involving pushing files though, 
but this is totally orthogonal to building images ;-)

This error is because the new gadget snaps that are compatible with
ubuntu-image have not yet been promoted to the stable channel; at the
moment, you must use -c edge instead to get the right version.

I don't know if there is anything blocking their promotion to the stable
channel at this point.  Michael, Oliver, can you comment?

Errors building custom ubuntu-core images

[Luke Williams]

Hello,

I am trying to build a custom ubuntu-core image with a custom kernel. Below
is my assertion:

{

  "type": "model",

  "authority-id": "",

  "brand-id": "",

  "series": "16",

  "model": "pc",

  "architecture": "amd64",

  "gadget": "pc",

  "kernel": "onl-kernel_3.18.25_amd64.snap",

  "timestamp": "2016-10-13T22:26:50+00:00"

}

I the sign the assertion and have a valid assertion model, but when I try
to build, I get the following error:


$ sudo /snap/bin/ubuntu-image -c stable -o onl-snappy.img --extra-snaps
onl-kernel_3.18.25_amd64.snap pc.model

Fetching core

Copying "onl-kernel_3.18.25_amd64.snap" (onl-kernel)

It almost looks like the gadget snap is no longer called pc, but I cannot
find in any past threads or documentation what it was changed to.

Any help would be greatly appreciated.
