I'm unable to run AppImage applications

I’m unable to run AppImage applications in my system.

They were running smoothly, then I had to reinstall the system, and now they don’t work. The files are marked as executables of course.

It happens with ALL AppImage files, not just for a single application (so I can rule out a problem with a particular package).

I’ve tried to run them from CLI, but I get the following generic error:

~/Apps/FontBase> LANG=C bash FontBase.AppImage
FontBase.AppImage: FontBase.AppImage: cannot execute binary file
~/Apps/FontBase> 


Even running them with sudo isn’t helping.

When you’re troubleshooting an app you start manually, it’s useful to view the generated system log entries.

Recommend:

  1. Prepare to invoke your AppImage app, but don’t actually invoke yet.
  2. Open a console, elevate to root and run the following command which will display your system log entries in real time
journalctl -f
  1. Now, invoke your AppImage app and view your results in the console running journalctl, you will see only what is related to your fail.

Thank you, I already managed to solve this by changing permissions to “usr/bin/fusermount”, as described here:
