Providing desktop applications to multiple Linux-based target systems (distributions) can be cumbersome. Whereas upstream application authors have always had the possibility to offer downloads for Windows and
macOS, distributing packages for Linux has traditionally required a lot of additional duplicated effort from maintainers, and does not scale well beyond the core set of applications that are part of the

Lately, application bundle formats like AppImage, Flatpak, and Snap have gained popularity in the Linux world, with Linux Torvalds calling AppImage “just great” and users appreciating the ease of the “one app =
one file” concept.

Providing an application in AppImage format can have many advantages:

  • Just one format for many major distributions like openSUSE, Ubuntu, Fedora, CentOS, Debian, and others
  • Super simple for users: just download one file, make it executable, and run
  • No unpacking or installation necessary
  • No root needed
  • No system libraries changed
  • Works out of the box, no installation of runtimes needed
  • Optional desktop integration with appimaged
  • Optional binary delta updates (only download the bytes that have changed between builds)
  • GPG signatures (inside the file)
  • Works on Live ISOs and when booting into multiple different distributions

On the flipside, it has been argued that distributing application bundles places additional burden on upstream application authors, who now also need to keep the bundled libraries up-to-date. Tools used by distributions can greatly mitigate this, by ensuring reproducible, up-to-date builds from trusted sources.

In this talk, Open Build Service lead developer Adrian Schröter and AppImage lead developer Simon Peter illustrate the challenges around providing quality application bundles and how they can be solved by
using proven distribution methodologies such as those provided by the Open Build Service.



Your desktop application as a cross-distribution AppImage
Using OBS and AppImage

Let’s bundle your desktop application as a cross-distribution “one app = one file” AppImage. In this workshop, you will learn from AppImage lead developer Simon Peter and Open Build Service lead developer Adrian Schröter how to build your application in a reproducible, secure way, and how to distribute it in the AppImage
format, including digital signatures and binary delta updates.

What to bring: Your desktop application, ideally already building on Travis CI or Open Build Service. A notebook. An open mind, persistence, and willingness to experiment.

(Free registration is required for the workshop.)
