Installing PhantomJS 2.x on Ubuntu is done manually at present. Here's a recipe I like.

• Download PhantomJS latest stable http://phantomjs.org/download.html
• Extract tarball contents into /usr/local/share
• In this example, latest tarball is named phantomjs-2.1.1-linux-x86_64.tar.bz2 and will extract to /usr/local/share/phantomjs-2.1.1-linux-x86_64

PHANTOM_JS_FILES=/usr/local/share/phantomjs-2.1.1-linux-x86_64
sudo ln -s ${PHANTOM_JS_FILES}/bin/phantomjs /usr/local/share/phantomjs
sudo ln -s ${PHANTOM_JS_FILES}/bin/phantomjs /usr/local/bin/phantomjs
sudo ln -s ${PHANTOM_JS_FILES}/bin/phantomjs /usr/bin/phantomjs

Append ?hotreload=true to the page URL (assuming this only works in dev mode)

Example:
