vagrant init bento/centos-6.8を入力するとエラーと出ます。


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)'
