I am still new to all of this and I am quite frustrated. I initially got my VM setup with Linux with no problems, however I was on my wife’s laptop and I needed to do it on mine. I setup the VM, downloaded Linux and I am currently trying to setup guest additions however I am stuck on one of the last steps. The instructions are telling me to enter “sudo /media/$USER/VBox*/VBoxLinux*.run”. I have checked over and over and have confirmed I am entering it correctly. I keep getting "sudo /media/$USER/VBox*/VBoxLinux*.run:Command Not Found. I looked in the actual file: Filesystem>Media>user, and it is empty. Is this right? Anyone have any suggestions?
