 These builds use a mechanism called [url=https://appimage.org/]AppImage[/url] which should allow these builds to run on most Linux distributions. However, we recommend that you compile your own builds which will result in less issues.
 Alternatively, if there is a package in your software repository then you should use that. If you are the maintainer of such a package for a distribution then let us know and we will include that here.
