% snapcraft promote --from-channel edge/hwacc --to-channel stable/hwacc chromium snapcraft promote does not have a stable CLI interface. Use with caution in scripts. No releases available for 'chromium' on channel 'latest/edge/hwacc' for architecture 'i386'. Ensure the selected channel contains released revisions for this architecture.
Why does it even matter if edge/hwacc has a i386 build to promote? I only need (and build) the amd64 snap.
How to work around that issue?
