Public bug reported:
With a fresh installed ubuntu server, you try to enable the http2
module, apache fails after restarting.
$ sudo a2enmod http2
$ sudo service apache2 restart
Viewing the logs I get:
Apr 08 12:23:30 1604srv apache2[21683]: apache2: Syntax error on line 140 of
/etc/apache2/apache2.conf: Syntax error on line 1 of
/etc/apache2/mods-enabled/http2.load: Cannot load
/usr/lib/apache2/modules/mod_http2.so into server:
/usr/lib/apache2/modules/mod_http2.so: cannot open shared object file: No such
file or directory
Checking why this file is missing from the package, so I downloaded the
source of the ubuntu package for 16.04
$ sudo apt-get source apache2
IF you install the package libnghttp2-dev before recompiling, the
mod_http2.so file is generated properly, and after installing my locally
compiled package, I can use HTTP/2 without any problem.
Note: When testing you might need to enable SSL and add "Protocols h2
http1.1" to the virtualhost. I added examples in this report.
My suggestion would be to add the libnghttp2-dev package to the build-
dep for the apache2 package.
Please note that this bug would affect the global adoption of HTTP2 if
the LTS distro is released with the module missing.
