make-snap Issue

This issue is happening on Ubuntu 20.04. My .DEB builds fine, but .SNAP has an issue. Almost like what I’ve seen here -> https://github.com/electron-userland/electron-forge/issues/1607

            },

              "audio": true,

            },
            "summary": "xxx",
            "description": "xxx"
          }
        }

An unhandled error has occurred inside Forge:

I haven’t tested this, but it probably works if you run Snapcraft 4.0 and you set base to core20.

Please don’t close this until we have a working solution.

Open issues in the issue tracker are for bugs and feature requests. This issue is effectively a support ticket.

Consider building the snap in an Ubuntu 18.04 VM or container (for example, the Docker container malept/electron-forge-container:node-10). Snapcraft seems to be launching its own VM and strange things are happening, which are outside the scope of Electron Forge.

So are you basically saying that Electron Forge can’t be used right now to develop Snap apps on Ubuntu 20.04 LTS? This should be stated on your website. Especially when all I did was follow your guide from scratch.
