libapache2-mod-shib2 will not install

[David Reagan]

When installing libapache2-mod-shib2 on 11.10 for the first time, I get the following:

It sounds like this bug: https://bugs.launchpad.net/ubuntu/+source/shibboleth-sp2/+bug/884402 which was fixed in shibboleth-sp2 - 2.4.3+dfsg-2ubuntu1. But that package is not available for 11.10. According to packages.ubuntu.com it is available for 12.04, but I can't upgrade to that yet.

Following the instructions from https://bugs.launchpad.net/ubuntu/+source/shibboleth-sp2/+bug/884402/comments/6 allowed me to install with this output:

===================================

So, apparently, the problem is fixed in 12.04, but still broken on 11.10. If I could upgrade to 12.04, I would. But I can't do that yet.
