How to activate support for AppImage in Ubuntu

AppImage on Ubuntu

The type of packaging AppImage It's the kind of thing that doesn't make much noise, but it's there. If we take a walk through GitHub or GitLab and look for any application for Linux, it is likely that we will find a tarball, .deb packages (Debian/Ubuntu and derivatives), .rpm (from Red Hat, for Fedora, openSUSE, CentOS, etc., and derivatives) and also its AppImage, which are the closest thing to apps Portable Windows and even better.

A application portable Windows is practically the same as if we install an application, take the folders it creates and take it with us on a USB. It is common for everything to be in a folder and inside there are several files, and you can find dozens. In AppImages there is only one file, an executable, and they can be opened with a double click. The problem is that this does not work like this in Ubuntu, at least in the main edition with GNOME.

Install the package that activates AppImage support in Ubuntu

Although Ubuntu is the base of many distributions, what is explained here is for editing with GNOME. Kubuntu opens it directly, and you don't even need to allow it to run as a program. It does ask us if we want it to be executed when doing Double click, but everything is simpler than in the main edition.

Still, the process is not complicated either; you just need to know the name of a package and take an extra step. He package name is libfuse2, and can be installed by opening a terminal and typing:

sudo apt install libfuse2

What would be left would be to right click on the AppImage and activate the option to run as a program. This step is also necessary in flavors like Budgie, but here it is not necessary to install libfuse2.

Another option is to use AppImage Launcher, which is an application prepared to manage this type of packages in Linux. In Article that Damián shared some time ago there is more detailed information, but what it does is integrate the applications into the operating system, which even moves them to their own folder, and it is also easier to uninstall them. It is software that makes things easier, but for those who think something more basic is better, they can be opened as we have explained above.
