Issue packaging hyper under Arch Linux

I can't package hyper under Arch. I installed libicns, graphicsmagick, xz and rpmextract and also had to install xorriso as I was having an issue with that. But it still fails with

Start with the reported yarn run dist command and the electron-builder Snap target referenced in node_modules/electron-builder/src/targets/snap.ts. Reproduce the Arch Linux packaging failure and determine how the missing snapcraft executable is expected to be handled. Done means the packaging workflow reaches completion without the reported spawn snapcraft ENOENT error.
