AppImage Installation

AppImage is a portable application format that works across many Linux distributions without system installation. Available for x86_64 systems only.

1. Install FUSE (Required)

AppImages require FUSE (Filesystem in Userspace) to mount and run. Install the appropriate package for your distribution:

Ubuntu/Debian/Linux Mint
sudo apt install fuse libfuse2
Fedora/RHEL/CentOS
sudo dnf install fuse-libs
Arch Linux
sudo pacman -S fuse2

2. Download and Run

1. Download the AppImage
Download RimuSDR-<version>-x86_64.AppImage to your Downloads folder from the link provided.
2. Make it executable
cd ~/Downloads
chmod +x RimuSDR-<version>-*.AppImage
3. Run the application
./RimuSDR-<version>-*.AppImage
Optional: Move it to ~/.local/bin/ for easy access from anywhere.
Troubleshooting: If AppImage Won't Run

If FUSE isn't available or you can't install it, you can extract and run the AppImage manually:

  • 1. Extract./RimuSDR-<version>-x86_64.AppImage --appimage-extract
  • 2. Run extracted./squashfs-root/AppRun
System Dependencies

RimuSDR AppImage requires the following system libraries (typically pre-installed):

  • FUSERequired to mount AppImage (libfuse2 or fuse-libs)
  • AudioPulseAudio or PipeWire, PortAudio
  • GraphicsX11 or Wayland display server with drivers
  • Coreglibc, OpenSSL (standard on most distributions)
