I installed Musescore v 3.3.4. on Ubuntu 18.04.3 LTS. When I try to open file from folder /media, I get message "Permission denied".
I tried to connect removable media by this:
sudo snap connect musescore:removable-media
but I got this:
error: snap "musescore" has no plug named "removable-media"
Does anyone have any idea please?
