Vagrant was unable to mount VirtualBox shared folders

[macidev]

Hi,

on my Mac (10.13.6) with Vagrant 2.2.5 and Virtualbox 6.0.8 I got after a working installation and restarting the vagrant machine following error:

Vagrant was unable to mount VirtualBox shared folders. This is usually because the filesystem "vboxsf" is not available. This filesystem is made available via the VirtualBox Guest Additions and kernel module. Please verify that these guest additions are properly installed in the guest. This is not a bug in Vagrant and is usually caused by a faulty Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: No such device

The issue only occurs, if I restart, after install the box is working fine, but with vagrant ssh a restart is required.

If there's anything further you need, please let me know.

This seems to be an issue with your vagrant installation. Please make sure, that you have all necessary plugins installed to use shared / synced folders.

install: vagrant plugin vbguest

Installing the vbguest didn't work. So I searched for a solution. After I installed https://github.com/dotless-de/vagrant-vbguest locally on my Mac, setting

Vagrant.configure("2") do |config| config.vbguest.auto_update = true end

in my ~/.vagrant.d/Vagrantfile and after that a vagrant up -> all went fine. Thanks.
