Authors: AppImage


Usage

AppImageUpdate is available as an AppImage which means "one app = one file", which you can download and run on your Linux system while you don't need a package manager and nothing gets changed in your system. Awesome!

AppImages are single-file applications that run on most Linux distributions. Download an application, make it executable, and run! No need to install. No system libraries or system preferences are altered. Most AppImages run on recent versions of Arch Linux, CentOS, Debian, Fedora, openSUSE, Red Hat, Ubuntu, and other common desktop distributions.

Running AppImageUpdate on Linux without installation

Unlike other applications, AppImages do not need to be installed before they can be used. However, they need to be marked as executable before they can be run. This is a Linux security feature.

Behold! AppImages are usually not verified by others. Follow these instructions only if you trust the developer of the software. Use at your own risk!

Download the AppImageUpdate AppImage and make it executable using your file manager or by entering the following commands in a terminal:

chmod +x ./*.AppImage

Then double-click the AppImage in the file manager to open it.

Sandboxing AppImageUpdate

If you want to restrict what AppImageUpdate can do on your system, you can run the AppImage in a sandbox like Firejail. This is entirely optional and currently needs to be configured by the user.

Updating AppImageUpdate

If you would like to update to a new version, simply download the new AppImageUpdate AppImage.

The AppImageUpdate AppImage also can be updated using AppImageUpdate. Using this tool, AppImageUpdate can be updated by downloading only the portions of the AppImage that have actually changed since the last version.

Integrating AppImages into the system

If you would like to have the executable bit set automatically, and would like to see AppImageUpdate and other AppImages integrated into the system (menus, icons, file type associations, etc.), then you may want to check the optional appimaged daemon.


Note for application authors

Thanks for distributing AppImageUpdate in the AppImage format for all common Linux distributions. Great! Here are some ideas on how to make it even better.
