1. Get AppImage(s)

First, you need to have some AppImages. Nowadays, many Free Software projects already allows you to download AppImages version of their applications and games officially from their websites. Here's some example. 

- FreeTube a youtube desktop client

- LibrePCB electronic schematics design

- SimulIDE electronic simulator and programmer with a lot of examples

- OpenRA strategy game similar to Red Alert

2. Test run an AppImage. 

Right-click inside the folder -> Open in Terminal -> execute an AppImage -> see whether the application runs  -> if not, see the error messages -> on Ubuntu 24.04 there is a known error where some required packages were not installed.

Sample command lines:

$ ./librepcb<whatever>.AppImage
$ ./freetube<whatever>.AppImage
$ ./OpenRA<whatever>.AppImage
$ ./SimulIDE<whatever>.AppImage

Sample output:

dlopen(): error loading libfuse.so.2

AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE
for more information

On Terminal, install the required packages for Ubuntu 24.04:

Command line:

4. Run AppImage again.

Once required package(s) installed, you now can run the AppImage again like normally you did with previous Ubuntu versions. You can simply double-click the file or repeat the execution commands above.

Sample command:

$ ./librepcb<whatever>.AppImage
$ ./freetube<whatever>.AppImage
$ ./OpenRA<whatever>.AppImage
$ ./SimulIDE<whatever>.AppImage

Now you should be able to run all AppImages. Happy hacking!
