AppImage Not running Ubuntu | Solution

Did you know that AppImages rely on FUSE technology to create a virtual file system?

FUSE, is short for Filesystem in Userspace.

In fact, this enables seamless interaction with the underlying system.

Unfortunately, sometimes we will run into trouble if there is a version mismatch with FUSE, especially on newer versions of Ubuntu.

For instance, Ubuntu 22.04 and later editions come with FUSE 3, while AppImages are tailored to work with FUSE 2. This is why AppImages fails to launch properly.

Fortunately, we can easily resolve the issue by installing FUSE 2 alongside FUSE 3, without risking any conflicts. Here’s how you can do it:

1. First, open a terminal window.
2. Then, run this command to install the libfuse2 package:

   sudo apt install libfuse2

If unsure about the Ubuntu version, run this command in a terminal:

lsb_release -a

Double-Checking Permissions

While resolving the FUSE issue often does the trick, it is also a good idea to check that the file permissions are correctly set. Here’s how you can verify:

1. To begin with, go to the AppImage file in the file manager.
2. Then, right-click on the file and choose “Properties” or “Get Info,” depending on the desktop environment.
3. Next, make sure the checkbox for “Allow executing file as program” is selected in the Permissions tab.

After installing libfuse2 and verifying the permissions, it’s time to give the launch AppImage.

With the above troubleshooting steps, we will soon have AppImages running with no trouble at all on Ubuntu.
