I have a windows 7 host where I'm using a Virtualbox 5.2.8. On this Virtualbox I've installed a VM with Ubuntul Server 16.04 and the Guest Additions from this version of virtualbox and I'm trying to share a directory.
Everything is properly set from virtualbox's side, the shared directory it's also present on /media path from ubuntu but unfortunately I can't mount it to be able to see the files from that shared directory (even if it has some files, on ubuntu it's seen as empty).
To mount it, I'm running this command:
ben@ubuntu:/mnt$ sudo mount -t vboxsf angfiles shares
/sbin/mount.vboxsf: mounting failed with the error: Protocol error
I already have the /mnt/shares directory.
Can you help me please with a hint to solve this issue?
