fatal: could not create work tree dir 'MagicMirror'.: Read-only file system

[Iron_Reptar]

I get this error while running the command

bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)"

that I got from the GitHub repo. This happens right after I get the notification that says
“Note.js installation Done!
Cloning MagicMirror…”

Any advice on how to fix this? I’m not familiar much with linux so any help is appreciated :)

@Iron_Reptar Just for fun I decided to try to rerun the command again, and it first said that “dpkg was interrupted.” so I ran
sudo dpkg --configure -a
Like the screen told me to, then re-re-ran it, to arrive at the error "E: Sub-process /usr/bin/dpkg returned an error code (1).
Help, all I want is a working mirror :(
