How to fix error in Vagrant (not find compatible versions for gem "nokogiri")?

Question

linux

Good afternoon.
Linux Ubuntu 16.04. Vagrant (1.8.0) when starting
$ sudo vagrant plugin list

ffi (1.9.18)
nokogiri (1.6.3.1)
vagrant-share (1.1.6, system)
vagrant-vbguest (0.13.0)

$ sudo vagrant up --provider libvirt

The provider 'libvirt' could not be found, but was requested to
back the machine 'default'. Please use a provider that exists.

$ sudo vagrant plugin install libvirt

The plugin(s) can't be installed due to the version conflicts below.
This means that the plugins depend on a library version that conflicts
with other plugins or Vagrant itself, creating an impossible situation
where Vagrant wouldn't be able to load the plugins.

You can fix the issue by either removing a conflicting plugin or
by contacting a plugin author to see if they can address the conflict.

Vagrant could not find compatible versions for gem "nokogiri":
  In Gemfile:
    vagrant (= 1.8.0) ruby depends on
      nokogiri (= 1.6.3.1) ruby

    libvirt (>= 0) ruby depends on
      nokogiri (~> 1.4.3) ruby

    nokogiri (>= 0) ruby

Answer 1

gem install nokogiri
