Using AppImage packages

An AppImage is a universal software package format valid for all common Linux distributions. Just download the LenMus appimage file, make it executable, and run it! No need to install. You can run LenMus anywhere including live disks.

See this YouTube video.

How to use the AppImage

• Download the AppImage file.
• Make it executable. By default, the downloaded AppImage file won’t have the execution permission. You’ll have to change that permission. You don’t need root privileges. Two methods for this:
  • The graphical approach is to right click on the downloaded .appimage file, select Properties, go to the Permissions tab and check the box that says “Allow executing file as program”.
  • The other alternative is to open a terminal window and to enter:

    cd <path/to/AppImage_file>
    chmod u+x <AppImage_file>
    

• Run it. Either:
  • double click on the downloaded .appimage file; or
  • open a terminal window and enter:

    cd <path/to/AppImage_file>
    ./<AppImage_file>
    

• If you are going to use the program regularly, create a shortcut in the menu or on the desktop. It is more practical!
