virtualbox change permissions on shared folder

Perryg wrote:You will find permission issues using the automount feature as they are handled differently in removable media by the OS. Why isn't it working? Now, I realize that I cannot use things like chmod on the actual files which are inside of the sf_Music, since those files are residing on the actual windows machine, which doesn't support the permission scheme, but I am not trying to change perms on those files, I only want to change them on the sf_Music directory itself. When I try to use the ACLs (setfacl) on sf_Music, then I get the operation invalid error (it works fine on other folders). The command executes with no error, but when I check the permissions on sf_Music, they are still 770.

I tried commands such as 'sudo chmod 777 /media/sf_Music'. The problem is that I am unable to change any permissions for that folder, which is set to 770 by default.

When I boot up the Ubuntu, the Music folder is correctly mounted as /media/sf_Music. In the Virtualbox settings I have added a shared folder with the name 'Music' and set it to be permanently and automatically mounted by checking the two check boxes. I have installed the Ubuntu server 16.04 (along with guest additions) as a guest OS on my windows machine.
