I'm running Lubuntu on Virtualbox on a PC. I've shared a folder (via the Lubuntu menu) on my PC so that I can transfer files to and from my Lubuntu instance.

However, when I try opening it I get the following error:

Error opening directory “/media/sf_MOVIES_AND_SERIES”: Permission denied.

Any ideas?


  • add your user to the vboxfs group

  • if MOVIES_AND_SERIES directory is also mount point on host OS, try to change shared folder path into a directory in MOVIES_AND_SERIES.

Any ideas?

Check help

For Linux and Oracle Solaris guests, access is restricted to members of the group vboxsf

Add user to vboxsf group

sudo adduser <username> vboxsf

    That gave some sort of an error ( I don't remember what exactly), so I continued looking and this worked: sudo usermod -G vboxsf -a username ln -s /media/sf_shared/ name_of_link.

    @Gottano after running sudo adduser myUserName vboxsf, I restarted the VM and it worked for me.
