[Documentation and/or app improvement] Inform Linux users that "File System in Userspace (FUSE) v2 libraries" are necessary

[Tentos]

Dear Internxt developers,

I am using Fedora 43. When I followed the AppImage documentation, the launch of the AppImage did not work and resulted in an error message on the command line. After some research, I realized that the package fuse-libs was missing on my Fedora installation, which could easily be installed. Afterwards, the AppImage has been fully functional.
This package contains the "File System in Userspace (FUSE) v2 libraries," see https://packages.fedoraproject.org/pkgs/fuse/fuse-libs/index.html .
It seems that the "File System in Userspace (FUSE) v2 libraries" have different names on different distributions and that they are not always installed by default.

Can the documentation be improved so that Linux users are informed that the libraries are necessary and how to install them on the most popular Linux distributions?
I would also suggest that the AppImage shows an info message when the libraries are missing.

Thank you for the Linux app. I hope that an rpm or a Flatpak version will be available soon.

I have used Lumo to generate a quick overview (as it is a GenAI answer, it may contain errors):

Installing FUSE v2 on the Most Popular Linux Distributions

Distribution	Package(s)	Installation command	Note
Debian 11/12 (and derivatives such as Ubuntu 20.04‑22.04)	libfuse2, libfuse-dev, fuse	bash sudo apt update && sudo apt install libfuse2 libfuse-dev fuse	On newer Ubuntu releases libfuse2 is still available; libfuse3 is provided separately.
Fedora 38	fuse-libs, fuse-devel	bash sudo dnf install fuse-libs fuse-devel	The fuse3 package also exists, but fuse-libs supplies the v2 library (libfuse.so.2).
Arch Linux	fuse2	bash sudo pacman -Syu fuse2	Arch separates v2 (fuse2) and v3 (fuse3) cleanly.
openSUSE Leap 15.5 / Tumbleweed	libfuse2, fuse-devel	bash sudo zypper install libfuse2 fuse-devel	libfuse2 provides the runtime library; fuse-devel gives the headers.
Gentoo	sys-fs/fuse:2	bash sudo emerge sys-fs/fuse:2	The :2 slot explicitly selects the v2 version.
Alpine Linux	fuse (musl‑based variant)	bash sudo apk add fuse	Alpine uses the same libfuse.so.2; development headers are already included.

Optional post‑installation steps

1. Add your user to the fuse group (if required):

sudo usermod -aG fuse $USER
# Log out/in or run `newgrp fuse` for the change to take effect

(Note: It was not necessary on Fedora 43.)
2. Verify that the library can be loaded:

ldconfig -p | grep libfuse
# Expected output: libfuse.so.2 => /usr/lib/libfuse.so.2 (or a similar path)

Hi @Tentos, thanks for reaching out!
You are right, I have updated the readme with both explaining which linux distros the app is currently compatible with and which version of fuse is necessary.

As of right now, our focus is on ensuring a solid experience forubuntu/Debian with Nautilus(or also called Files) File explorer, while we are not closing the door on broader distro support or bringin aditional packaging formats, we first want to make sure that the core experience is as good as can be.

Again, thanks for reaching out and helping us make the App better!
