upgradeした。再度versionを確認したところ下記のようであった。

$ vagrant version
Vagrant failed to initialize at a very early stage:

The plugins failed to initialize correctly. This may be due to manual
modifications made within the Vagrant home directory. Vagrant can
attempt to automatically correct this issue by running:

  vagrant plugin repair

If Vagrant was recently updated, this error may be due to incompatible
versions of dependencies. To fix this problem please remove and re-install
all plugins. Vagrant can attempt to do this automatically by running:

  vagrant plugin expunge --reinstall

Error message given during initialization: Unable to resolve dependency: user requested 'vagrant-vbguest (> 0)'
$

使用しているプラグイン”vagrant-vbguest“がどうやらダメだったようだ。出力されたメッセージにあるとおり実行してみる。
