This fails to build and has conflicts with the main branch. @ThyMYthOS do you want to continue working on it, or should we close this PR?

[ThyMYthOS]

The version is outdated anyway. I will give it another try using your suggestions.

@merlijn-sebrechts seems that source-checksum does not support advanced grammar. Any idea how to solve this?

It seems like it's building on X86_64!

Have you tested this on arm yourself? If you don't have an arm device, you can use remote-build to build on the launchpad builders from your local machine: https://snapcraft.io/docs/remote-build

Alternatively, you could modify the GitHub action to also build on arm, like we do for gimp: https://github.com/snapcrafters/gimp/blob/master/.github/workflows/build-prs.yml

How do you want to proceed?

I just built this locally for amd64, and also tested remote-buiild for arm64 and it's all good! I'll merge this and follow up another time with a CI uplift to follow the latest actions. Thanks!

Edit: heh, I can't merge unless there is another review.

Build logs for arm64 attached.
