I was unable to free up disk space on my Raspberry Pi recently, and I kept getting a "cannot remove... Read-only file system" error when attempting to run the `rm` command. The following step was necessary prior to then removing uncessary files and freeing up space on the filesystem. 

`sudo mount -o remount,rw /`
