Hi. I just installed MuseScore 2 as an AppImage because of some dependency problems with KDE Neon. The install went fine, but the kbuildsycoca4 won't quit and I am wondering if I should kill the process using "Control C". The AppImage install process is described here:

https://musescore.org/en/handbook/install-linux#AppImage-install

Can I kill the process without damage? Here is the output as it stands:
