We'd love some community support to help us support some of the common linux distribution channels.

This ticket is for supporting AppImages.

If you are interested in helping us support this distributable format please let us know!

I don't know if I'll have the time to maintain this, but I decided to see how easy this would be.

I followed DistroTube's tutorial, and successfully created a package for Ghostery. I created this with the second-most-recent release to see if updates would work.

The problem came up when I launched the appimage. It seems to function fine, but it gave me this error:

I believe that appimages have their own way of updating via AppImageUpdate, so we'd either have to:

1. have to disable the normal update code to set up AppImageUpdate,
2. figure out how to update the AppImage via the built-in Ghostery update process, or
3. disable updating altogether.

TLDR: Packaging the program is simple, updating it is harder
