Our current autoupdating framework only supports MacOS and Windows even though we also build the app for Linux. Our current behavior for Linux is to simply notify the user if an update exists and, if they choose to, navigate them to our releases download page so that they can download and install the latest themselves (#870).

To support Linux autoupdates would require a shift to a new packaging and updating framework. After a quick search, one option could be to use https://www.electron.build/ and https://www.electron.build/auto-update though it would be worthwhile to research options in more depth since swapping out our current build and packaging layer would be a significant change.
