Answer 1

phantomjs 2.1.1 is now currently bundled with 16.04 (https://launchpad.net/ubuntu/xenial/+source/phantomjs), so you should be able to install/upgrade it as a system package.

Update: This answer exists for informative purposes, but it is not recommended to use the system package version now due to issues such as: https://bugs.launchpad.net/ubuntu/+source/phantomjs/+bug/1605628 This is related to an issue with file upload that was fixed upstream, but the nature of the fix prevented it from working as a system package.

The best current option is use the prebuilt binary from: https://bitbucket.org/ariya/phantomjs/download
