Resolving the dlopen() Error with Appimage on Arch Linux

The allure of an Appimage can quickly turn into frustration when an unexpected roadblock presents itself. You’re greeted by a discouraging “dlopen() error.” This error, often tied to loading “libfuse.so.2,” can be a stumbling block, especially when dealing with applications that rely on FUSE (Filesystem in Userspace) features.

  1. Install fuse2 Using pacman:

    open your terminal and executing the following command:

    sudo pacman -S fuse2

    This essential step ensures that the necessary FUSE library, including “libfuse.so.2,” is readily available, thus paving the way for uninterrupted usage of FUSE-dependent applications.

  2. [Optional] Install fuse and squashfuse:

    While not obligatory, this step can further enhance compatibility and provide a comprehensive approach to handling FUSE-related operations. You may choose to install fuse and squashfuse for an extended range of functionalities:

    sudo pacman -S fuse squashfuse

    Please note that this step is optional and primarily caters to specific use cases.

That is the fix: install fuse2, plus fuse and squashfuse if you want them, and the dlopen() error goes away because the dependencies it complains about now exist.

How It Works

These libraries let FUSE-based applications talk to your filesystem as if they were running at the kernel level. Once they are present, the Appimage loads its libraries normally and the dlopen() error stops.
