Failed Mounting VirtualBox Shared Folders in an Ubuntu 17.04 Guest

  • 772

I have a folder in my Windows 10 host that needs to be shared with the Ubuntu 17.04 Virtualbox Guest.

Here's what I did:

  1. Added the windows folder to the VM's Shared Folders Folder Lst (Name: scraper, Auto-mount: Yes, Access: Full, Machine Folder)

  2. Added user to vboxsf group

    sudo usermod -a -G vboxsf scraper

  3. sudo mount -t vboxsf -o uid=1000,gid=1000 scraper /mnt/the-scraper

and encountered this 

/sbin/mount.vboxsf: mounting failed with the error: No such file or directory

Why is this error happening? How can we solve this?

mount

  1. Best Answer

    You must log out, and log back in, for the vboxsf group to be enabled.

    No implicit mount is required. If your Windows folder shows up in the Shared Folder icon at the bottom of the VB window, you just need to open a Nautilus window and click on the shared folder name in the left pane, or, in the Shared Folder setting, indicate that it should auto-mount.

    Before doing your implicit mount, did you create the directory /mnt/the-scraper?

  2. What seems to have helped in my case (I needed to remount automounted dir ws with proper user as owner):

    1. Create directory that I wanted to mount it to (/mnt/rews):

      sudo mkdir /mnt/rews

    2. Set max permissions to the created dir:

      sudo chown artyhedgehog:artyhedgehog /mnt/rews
sudo chmod 777 /mnt/rews

    3. Got this error when tried mounting:

      $ sudo mount -t vboxsf -o remount,gid=1000,uid=1000,rw ws /mnt/rews     
/sbin/mount.vboxsf: mounting failed with the error: Invalid argument

    4. So I unmounted automount by VirtualBox and mounted back manually - and it worked:

      sudo umount ws
sudo mount -t vboxsf -o gid=1000,uid=1000,rw ws /mnt/rews

    P.S. Windows 10 on host, VirtualBox 6.0.8, Ubuntu 18.04 LTS on VM, VirtualBox Guest Additions installed via VirtualBox instance menu, Shared Folder set up with "Folder Name": ws, "Auto-mount": checked, "Make Permanent": checked.
