Error when running 'vagrant up'

[loumarven]

Issue:
vagrant up not working

This is the error I get when I run vagrant up:

Failed to restart thin.service: Unit thin.service not found.

Root cause:
Required(?) bundler version was not installed. Ran vagrant provision and got this error:

Could not find 'bundler' (1.17.3) required by your /vagrant/Gemfile.lock.

Solution:

1. ssh into the vagrant box with vagrant ssh
2. run the command sudo gem install bundler:1.17.3
3. type exit to exit from the ssh session
4. run vagrant provision
5. run vagrant up again and visit http://localhost:3000

Note:
Opened this issue in case others are experiencing the same and are looking for a solution

See PR #722. A fix for this is to edit Gemfile.lock, and change the last line at the bottom:

BUNDLED WITH
   1.17.3

to this:

BUNDLED WITH
    2.1.4

Rubygems seems to default to installing 2.1.4 now.
