Why is vagrant not mounting /vagrant? - linux

Question

I'm trying the simplest of vagrant configurations, but it is not mounting /vagrant as I would expect. The permissions of the local dir seem reasonable, and I don't se anything in the debug output that would give me a clue why.
$ ls -ld .; ls -la .; cat Vagrantfile; VAGRANT_INFO=debug HOME="$(pwd)" VAGRANT_HOME="$(pwd)" VAGRANT_CWD="$(pwd)" vagrant up
drwxr-xr-x 2 xxx xxx 25 Jul 30 14:44 .
total 4
drwxr-xr-x 2 xxx xxx 25 Jul 30 14:44 .
drwxr-xr-x 7 xxx xxx 80 Jul 30 14:23 ..
-rw-r--r-- 1 xxx xxx 78 Jul 30 14:44 Vagrantfile
Vagrant.configure("2") do |config|
config.vm.box = "generic/ubuntu2004"
end

I have tried adding an explicit synced_folder as described here:
Vagrant.configure("2") do |config|
config.vm.synced_folder = "/local/xxx/vagrant4/", "/vagrant"
config.vm.box = "generic/ubuntu2004"
end
But that causes an error:
vm:
* The following settings shouldn't exist: synced_folder
This is with vagrant 2.2.8:
$ vagrant --version
Vagrant 2.2.8

Answer 1

This is happening because synced_folder should be used like a function call, not an assignment. I don't see an easy way to tell which to use in the documentation, aside from examples, but this should work:
Vagrant.configure("2") do |config|
config.vm.synced_folder "/local/xxx/vagrant4/", "/vagrant"
config.vm.box = "generic/ubuntu2004"
end
