MuseScore 4 AppImage does not run on Ubuntu 24.04 LTS

• Apr 27, 2024 - 08:38

I have just installed the very latest Ubuntu 24.04 LTS distribution. While MuseScore 3 is included in that distribution, I have to use MuseScore 4 but it does not run. The command below worked just fine on my previous Ubuntu 22 distribution:

$ ./MuseScore-
dlopen(): error loading

AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
for more information

I previously installed the earlier beta versions of Ubuntu 24.04, same problem. I tinkered with the system a bit by uninstalling fuse3 and installing fuse2, which was sort of successful as I then could launch MuseScore 4 just fine, however after the next reboot the Linux desktop did not run. So I had to purge both fuse and gdm3, followed by a reinstall of gdm3 to get back access to the system.

Please advise what to do to install MuseScore 4 on Ubuntu 24.04 LTS.


I did not test Ubuntu 24.04 LTS (i will upgrade when 24.04.01 is available, mid August, as recommended by Ubuntu)
Why do you uninstall libfuse3? Why not Just install libfuse2 alongside libfuse3. (just like before on all recent Ubuntu distributions)

I installed the "fuse" package (that's how I interpreted the error message "AppImages require FUSE to run") however that uninstalls fuse3 along with lots of other desktop related packages:

# apt-get install fuse
The following packages will be REMOVED:
fuse3 gnome-remote-desktop gnome-shell-extension-desktop-icons-ng
gnome-snapshot gvfs-fuse nautilus ntfs-3g shotwell ubuntu-desktop
ubuntu-desktop-minimal ubuntu-session xdg-desktop-portal
xdg-desktop-portal-gnome xdg-desktop-portal-gtk
The following NEW packages will be installed:

I just installed libfuse2 as you suggested:

# apt-get install libfuse2t64

and that fixed the error when starting MuseScore 4. It also did not destroy the desktop configuration after reboot. Thanks!
