AppImage requires a 256x256 icon

[lucasfernog]

This line of code assumes that a 256x256 icon is built:

tauri/cli/tauri-bundler/src/bundle/templates/appimage

Line 13 in e8ecd3c

cp usr/share/icons/hicolor/256x256/apps/{{app_name}}.png {{app_name}}.png

Tauri by default ships a 128x128@2x icon so it always works under our template, but we should fix that.

@lucasfernog - did we ever resolve this?

I'll be updating the bundler config soon and will make sure this is fixed.

I still got the error:

thread 'main' panicked at /home/tomek/.cargo/registry/src/index.crates.io-6f17d22bba15001f/tauri-bundler-1.2.1/src/bundle/linux/appimage.rs:73:6:
couldn't find a square icon to use as AppImage icon
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I also encountered this error when trying to build my Tauri v2 app without specifying an icon in the bundle.icons field of the tauri.conf.json file.

Example

BEFORE

{
    ...
    "bundle": {
        "icons": []
    }
}

AFTER

{
    ...
    "bundle": {
        "icons": ["icons/Square310x310.png"]
    }
}
