Linux AppImage icon does not show up

[moughxyz]

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.

How do you start app? From menu or by clicking on file?

[moughxyz]

From the command line. Because there’s no way to click on AppImage to open it. chmod a+x standard-notes---.AppImage ./standard-notes---.AppImage Then Ubuntu asks if I want to save it to launcher, and I say yes. But then the icon is missing.

So I'm not sure I'm following: does this mean if the user launches it via the command line, it is impossible to show an icon? Or does adding an icon property in the BrowserWindow config fix this?

Oh wow, actually, this worked:

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