Vagrant Azure install fails

[bWilsher]

Host - Debain
Vagrant 2.2.3

When I attempt to run: vagrant plugin install vagrant-azure

I get the following error:

---

Bundler, the underlying system Vagrant uses to install plugins,
reported an error. The error is shown below. These errors are usually
caused by misconfigured plugin installations or transient network
issues. The error from Bundler is:

conflicting dependencies fog-core (> 1.43.0) and fog-core (= 2.1.0)
Activated fog-core-2.1.0
which does not match conflicting dependency (> 1.43.0)

Conflicting dependency chains:
fog-core (= 2.1.0), 2.1.0 activated

versus:
vagrant-libvirt (> 0), 0.0.41 activated, depends on
fog-core (~> 1.43.0)

I have tested my internet connection and it seems okay and I have also tried expunging plugins and reinstalling, neither fixed the issue.
