Bug Description

I am trying to run

$ snap prepare-image --channel=edge ./uc20.model $(mktemp -d)

it downloads things from wrong locations.

Ie. it gets snapd and core20 from "edge", but it also gets pc and pc-kernel from "edge". It should be using "20/edge" for pc and pc-kernel, as specified track field in the model.

uc20.model attached.

I think i worked around this by using "default-channel" key.

However, that fixes everything for me, but snapd itself. Ie. since i cannot list snapd in the model, i cannot specify "default-channel: edge" for it.

So I kind of need for --channel option to be inteligent, or be a "map" on per-snap basis. Or something like that.

Opened a separate bug about inability to specify snapd in the model, which imho now needs to happen explicitely, now that it's a stand alone snap.

I can confirm that 'track' is ignored atm. Having both track and defualt-track is confusing, and I'm sure it's a bug of some sort, but I'm not sure if the bug is having both, ignoring one and not the other, or not complaining when one is specified in a place it isn't expected. Something's confusing, for sure, and we should fix it.

Meanwhile, you can now have snapd in the model, so that works :-)
