Use specific Vagrant box version instead of the latest one.

Display Vagrantfile configuration. It will use the latest available box version.

$ cat Vagrantfile

But you can define a specific box version to use.

$ cat Vagrantfile
Vagrant.configure("2") do |config|
  config.vm.box         = "debian/buster64"
  config.vm.box_version = "10.20210228.1"

  config.vm.network :private_network, ip: "172.16.0.77"

  config.vm.provider :virtualbox do |v|
    v.memory = 2048
    v.cpus = 2
  end
end
$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'debian/buster64' version '10.20210228.1' is up to date...
==> default: Clearing any previously set forwarded ports...
==> default: Fixed port collision for 22 => 2222. Now on port 2202.
==> default: Clearing any previously set network interfaces...
==> default: Preparing network interfaces based on configuration...
    default: Adapter 1: nat
    default: Adapter 2: hostonly

    default: SSH address: 127.0.0.1:2202
    default: SSH username: vagrant
    default: SSH auth method: private key
==> default: Machine booted and ready!

This is useful at times, as things can go haywire after update.
