Vagrant sync folder doesn't work on windows 10 - vagrant

Question

I'm trying to sync folders from a windows 10 hosto to a ubuntu guest but I get this error:
$ vagrant up

Failed to mount folders in Linux guest. This is usually because
the "vboxsf" file system is not available. Please verify that
the guest additions are properly installed in the guest and
can work properly. The command attempted was:
mount -t vboxsf -o uid=`id -u vagrant`,gid=`getent group vagrant | cut -d: -f3`,nolock,vers=3 core /sync_workspace
mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant`,nolock,vers=3 core /sync_workspace
The error output from the last command was:
stdin: is not a tty
unknown mount option `nolock'
valid options:
rw mount read write (default)
ro mount read only
uid =<arg> default file owner user id
gid =<arg> default file owner group id

Here is my Vagrantfile
Vagrant.configure(2) do |config|
config.vm.box = "ubuntu/trusty64"
config.vm.network "forwarded_port", guest: 8080, host: 8080
config.vm.synced_folder "C:/Users/rafa/Documents/personal docs", "/vagrant_data/sync_workspace"
end
Host : Windows 10
Guest: Ubuntu
Vagrant: 1.8.1
VirtualBox : Version 5.0.20 r106931
Any Help?

Answer 1

Install the vagrant vaguest plugin and let it install the host's VirtualBox Guest Additions on the guest system and in your case it will update your guest addition

Answer 2

Also try apt-get update in your guest OS.
