Vagrant Error

vagrant_error

Error:

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 root`,gid=`getent group vagrant | cut -d: -f3` tmp_vagrant-puppet-3_manifests /tmp/vagrant-puppet-3/manifests
mount -t vboxsf -o uid=`id -u root`,gid=`id -g vagrant` tmp_vagrant-puppet-3_manifests /tmp/vagrant-puppet-3/manifests


Solution:

vagrant plugin install vagrant-vbguest
vagrant reload
