AppImage fuse error

[woile]

Hi everyone, thanks for this great project!

I'm trying to build an AppImage, and it works, but when actually running the AppImage in Ubuntu 24.04 I get the following issue:

AppImage requires FUSE to run

On Ubuntu it seems possible to fix it by installing:

sudo apt install libfuse2t64

Though ideally, the AppImage should just run.

Is there a way to fix this on cargo-packager? Looking at some other github issues it seems FUSE is required by appimagekit but instead appimagetool should be used. I was wondering what's the approach taken by cargo-packager? I couldn't find those 2 libraries being used in this project.

Best

linuxdeploy (or rather its built-in appimage plugin) is what uses appimagekit/appimagetool - luckily we can update the appimage plugin without requiring linuxdeploy to update its built-in version. will try to do that today.

as an aside, we may also completely replace the current appimage bundler with different tooling in the future as i do in tauri-bundler (which cargo-packager originated from) tauri-apps/tauri#12491

can you try using cargo-packager from this branch? #362 via

cargo install cargo-packager --git https://github.com/crabnebula-dev/cargo-packager --branch fix/appimage-plugin

I'll take a look at it and report back!

Same issue, here's the release: https://github.com/reciperium/temporis/releases/tag/v2025.07.29-01

I get:

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

(I've uninstalled libfuse2t64 to test it)

[woile]
