Linux AppImage icon does not show up

Hello, I’ve been using electron-builder for about a year now. It’s made my life tremendously easier.

Users have reported this issue for a long time, and I thought it was some user error. But no matter what I’ve tried, I can’t get the app icon to show up in any Linux distro. I’ve tested on Ubuntu and Fedora.

Here is what it shows (bottom):

Root package.json:

  "build": {
    "linux": {
      "category": "Office",
      "icon": "build/icon/",
      "target": [
        "AppImage",
        "deb"
      ]
    }
  }

My build folder in root:

build/
├── icon
│   └── Icon-512x512.png
├── icon.icns
└── icon.ico

My app/package.json does not have any icon related metadata. Should it?

Any other info I can share that might be helpful?

Here is the app repo: https://github.com/standardnotes/desktop/tree/backups

Using electron-builder 19.45.0.

Oh wow, actually, this worked:

win = new BrowserWindow({
   ...
   icon: path.join(__dirname, '/icon/Icon-512x512.png')
})

This fixed it for me if someone wants to see a live example in an open source app here is the commit https://github.com/szTheory/exifcleaner/commit/8a129a124d58c21b1f0aff3a79326b8b2d1ebf25

const createMainWindow = async function() {
	let options = {
		title: app.name,
		show: false,
		width: DEFAULT_WINDOW_WIDTH,
		height: DEFAULT_WINDOW_HEIGHT + 25,
		minWidth: DEFAULT_WINDOW_WIDTH,
		minHeight: DEFAULT_WINDOW_HEIGHT + 25,
		webPreferences: { nodeIntegration: true }
	};

	if (is.linux) {
		options = Object.assign({}, options, {
			icon: path.join(__dirname, "../../exifcleaner.png")
		});
	}

	return new BrowserWindow(options);
};
