When running the latest VictronConnect Linux AppImage (v6.34) on Fedora Kinoite 44 an error is reported and it fails to launch:
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
Fedora actually came by default with both FUSE 2 and 3 but since version 44 FUSE 2 is no longer included due to security concerns.
The option to run this AppImage and any other for that matter is to run it with the “–appimage-extract-and-run” parameter. This would simply extract its content directly on disk and delete it afterwards. Usually it would have run inside the FUSE virtual file system:
$ Downloads/VictronConnect-x86_64_v6.34.appimage --appimage-extract-and-run
The real solution would be for the Victron developers to use the latest AppImage which has FUSE 3 built-in.
