As a workaround you can recompile the client locally. I've just tried it and it's working just fine on Ubuntu 22.04 Clone the repo: git clone git@github.com:Jigsaw-Code/outline-client.git cd outline-client Install node 16 (for example using brew) brew install node@16 Install all dependencies npm install Build the app npm run action electron/build linux Now you have properly working Outline-Client.AppImage and you can run it ./build/dist/Outline-Client.AppImage

I am concerned with duplicated dependencies though, that's my primary aversion to flatpak/snap/AppImage/etc.

My biggest issue with snap is not the concept per se but that it's a mostly Ubuntu thing and FlatPak and AppImage are similar ideas. For once it would be nice if the Linux world would consolidate around a single technology instead of fragmenting like this.
