Enable HTTP2 in Apache on Ubuntu 16.04

Posted on May 11, 2016
Ubuntu 16.04 Apache Server Optimization
Asked by Florian Lehmuth

Hi there,

I’ve recently created a new droplet with Ubuntu 16.04 and was pleased to see that sudo apt-get install apache2 gets me Apache 2.4.18. I was hoping that would allow me to enable HTTP2 support; alas, the respective mod_http2 is not included. Is there any way to manually install the module or to get a version of Apache that has it included?

Many thanks, Florian

Another option is using Ondrej’s Launchpad PPA. For example: (replacing REPOSITORY with string from that page for your Ubuntu version).

sudo add-apt-repository 'REPOSITORY'
sudo apt-get update
sudo apt-get dist-upgrade

This will give you the latest Apache rather than the version specifically for Ubuntu. Of course there are reasons Ubuntu ships slightly differently - stability, known degree of security/performance testing etc. but in my mind it is a worthwhile tradeof especially for HTTP/2

a2enmod http2 perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_CTYPE = “UTF-8”, LANG = “en_US.UTF-8” are supported and installed on your system. perl: warning: Falling back to a fallback locale (“en_US.UTF-8”). ERROR: Module http2 does not exist!
