vagrant-vbguest プラグインが導入されていると発生するエラーとその対処法について。

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

Or you may want to try updating the installed plugins to their latest

vagrant plugin update

Error message given during initialization: Unable to resolve dependency: user requested 'vagrant-vbguest (= 0.20.0)'
