You must first turn off the guest computer before attempting this. That’s it! Once you’ve done all of that, you should be able to change the permissions on the shared folder without any problems.

For example, to make the shared folder readable and writable by everyone, you would run the command: sudo chmod -R a+rwx /path/to/shared/folder Replace “/path/to/shared/folder” with the actual path to the shared folder. Finally, change the permissions on the shared folder. Replace “username” with your actual username: sudo usermod -a -G vboxsf username 3. To do that, run the command: sudo groupadd vboxsf 2. First, check to see if the vboxsf group exists on your system by running the command: grep vboxsf /etc/group If the vboxsf group exists, you should see output like this: vboxsf:x:1001: If the vboxsf group doesn’t exist, you’ll need to create it.

Once you’ve done that, you should be able to change the permissions on the shared folder. The fix is simple – just add the vboxsf group to your system, and then add your user to that group. However, on many Linux systems, the vboxsf group doesn’t exist. By default, the shared folder is created with the owner set to the user that created it, and the group set to vboxsf. The problem is caused by a permissions issue with the VirtualBox shared folder. If you’re trying to change the permissions on a VirtualBox shared folder in Linux and getting the error message “You cannot change the permissions of the shared folder”, don’t worry – it’s a common problem, and there is a easy fix.
