Upgrade to JHipster 3.4.2 in Ubuntu 16

JHipster introduced a nice upgrade utility since version 3.4 but it seems it has some issue when you work in Ubuntu.
This is a workaround to get it working

Install JHipster in Ubuntu 16

JHipster

 

JHipster is a Yeoman generator that will kick start your AngularJS -Java Spring project. It can create all your user administration services (including facebook, twitter and google user types). It can create a bunch of files to handle your entities with a single command (Spring controllers, repositories, REST controller, Angular controllers, forms, views, dialogs and tests)
