Trellis hanging on installing dependencies

So obviously there’s some issue with NFS.
There’s two options:

  1. switch to another mount type (even just temporarily)
  2. Fix NFS

To try another mount type, create a vagrant.local.yml file and add this:

vagrant_mount_type: virtualbox

To fix NFS, according to the Vagrant docs, both the Linux host and guest need NFS installed. On the guest this should be done automatically, so I assume your host OS is missing it.

I’m not sure what OS you’re running, but on Ubuntu you can do sudo apt install nfs-kernel-server. Here’s a decent looking page on troubleshooting it more.

edit: in either case, I suggest destroying the VM first and starting again.
