Hi @nat1foot here is the solution posted by @osmplus_org . Let us know if this works for you:
The Solution:
The problem is that Ubuntu 24.04 no longer ships withlibfuse2by default, which is essential for running AppImages. To fix this, you just need to install the compatibility library via the terminal:
sudo apt update
sudo apt install libfuse2t64
After installing this package and ensuring the AppImage has execution permissions (chmod +x), the uploader works perfectly. I wanted to share this here in case anyone else runs into the same “silent” failure on newer Linux distributions.
Additional tip:
If installing libfuse2t64 does not solve the problem, you can also try running the AppImage without sandboxing (e.g. with --no-sandbox). In that case I recommend using a dedicated Linux machine or virtual machine that is used only for this application.
