dlopen(): error loading libfuse.so.2

Getting error when running aarch64 appimage on PI4

dlopen() error loading libfuse.so.2

It seems my PI4 Linux installation comes with libfuse.so.3 and appimage version depends on libfuse.so.2. Is there a way to update appimage dependency to libfuse.so.3 (I belive libfuse3 is now more common even in Ubuntu)

Hmmm... looks its an issue with AppImage itself unfortunately, and it doesn't look to have been resolved yet: AppImage/AppImageKit#1120
OpenShot/openshot-qt#4789

The only workaround for now would be to compile PsyDoom from source, or try with an older distro. Some have tried to install libfuse2 manually but that broke their distro... I may have to consider another packaging format for future releases.

This will be fixed in the final 1.2.0 release and is already fixed in the 1.2.0-preview1 build: https://github.com/BodbDearg/PsyDoom/releases/tag/preview-builds%2F1.2.0-preview1

The fix is to simply use the latest version of appimagetool when packaging PsyDoom, which eliminates the problematic libfuse dependency via static linking:
