Launchpad has API to choose a channel for Snapcraft: https://launchpad.net/+apidoc/devel.html#snap_build > channels (writeable) > Source snap channels to use for this build. > A dictionary mapping snap names to channels to use for this build. Supported snap names: 'core', 'core18', 'core20', 'core22', 'core24', 'snapcraft', 'snapd' Would be good to expose that on `remote-build`, and even better - default to whatever the local Snapcraft channel is, if possible.
