I am trying to install Webwork 2.8 on Ubuntu 14.04.

When I check the installed modules, Mail::Sender gave the following messages...

defined(@array) is deprecated at /usr/share/perl5/Mail/Sender.pm line 318.
(Maybe you should just omit the defined()?)
defined(@array) is deprecated at /usr/share/perl5/Mail/Sender.pm line 2693.

When I tried to restart Apache I saw similar messages and then a seg fault...

I possibly have a machine just like yours.
Ubuntu 14.04 runs apache2.4 as opposed to 2.2; there are issues here.
I got past the apache issue: sort of.
Much discussion on the forums here.
I then had all the library browser 2 issues that have also been discussed on the forum.
Currently the machine is literally "shelved"; every now and again I update the 2.9 branch and am sure that someday it will work again.
It seems that backward compatibility in the Linux world is not a priority.
sorry for not being more helpful

I tried the apache2.4 conf file in the develop branch but still seg faults.

I'm in the exact same boat: Ubuntu 14.04; WebWorK 2.8; using webwork-apache2.4-config to no avail.

If Apache 2.4 is the problem what about compiling Apache 2.3 from source
on Ubuntu 14.04 and trying that?

Do your segfaults only occur when you are viewing a problem with pictures?

Do you also have php compiled into apache?

If so you might have a conflict with libgd which is the package that draws the on the fly graphics.  It has to be installed carefully if you also install php.

type libgd into the forum search box and look at the comments to see if some of them might apply to your case.

Regarding pictures.....I was never able to start Apache 2.4+Webwork
to able to able to do anything with pictures.

Regarding PHP, I'm just using the vanilla Ubuntu 14.04 that Amazon EC2 instances come with.  If the stock Apache2.4 has PHP conflicts should everyone remove the Apache package and compile from source without PHP turned on?

I've commented the entire webwork-apache2.4-config file and am uncommenting line by line, running service apache2 reload after each uncomment. The crash first occurs when I uncomment line 38:

require Apache::WeBWorK; # force compilation of pretty much everything

If I comment out that line, I can uncomment the entirety of the <Perl>...</Perl> section.

When I then uncomment line 65:

PerlModule WebworkSOAP
