The easiest way to install the program is by using an AppImage:
Steps 7 and 8 ensure that a MuseScore entry appears in the system’s menu and is linked to the new location of the AppImage (/home/[user name]/.local/bin). The correct file associations are also automatically made.
Note: Instead of steps 7 and 8 (above) you can, of course, install using the absolute file path instead. That is:
Tip: if you apply copy to the AppImage and press Ctrl+Shift+V in the terminal this will enter the absolute file path of the file that has just been “copied”.
No formal uninstall procedure is needed to remove the installed AppImage. Just delete menu entries and any shortcuts manually, then delete the App itself, and its links (which will be in ~/.local/bin).
