This has probably been around for a while but I just discovered it today.Musescore download
If you're running ANY Linux distribution, Red Hat, Centos, Linux Mint, Debian, Ubuntu, Fedora, Suse... pick your distribution, pretty much anything that's running Linux.
Download the appimage and you can run the latest Musescore without having to install it and without needing system root rights.
Just run the file that you downloaded. For example, if you have a 64-bit system (which most of us have in today's world) download the 64-bit appimage and do this:
Open a terminal window, go into the directory where the appimage is located.
Type "chmod 754 MuseScore-3.4.2-x86_64.AppImage" (without the quotation marks)
Type "./MuseScore-3.4.2-x86_64.AppImage" (without the quotation marks)
And there's the latest musescore program up and running. The program just runs from within its container file. The appimage file contains all of the resources that are needed for the program to run, regardless of what other programs or libraries may or may not be installed on your computer. And they just stay in the container file, nothing is installed on your computer.
The whole thing is just as slick as all get-out.
