Install script failing

This doesn't look like a fresh install to me:

> install:
> Source (Distribution) Directory (press <enter> to accept default): [/opt/shibboleth-identity-provider-4.2.1] ?
> 
> Installation Directory: [/opt/shibboleth-idp] ?
> 
> INFO  - Including auto-located properties in /opt/shibboleth-idp/conf/c14n/subject-c14n.properties

In a fresh install you should have a whole dialog between these two lines:


> [/home/rdw/tmp/shibboleth-identity-provider-4.2.1/bin$ ./install.sh
> Buildfile: /home/rdw/tmp/shibboleth-identity-provider-4.2.1/bin/build.xml
>
> install:
> Source (Distribution) Directory (press <enter> to accept default): [/home/rdw/tmp/shibboleth-identity-provider-4.2.1] ?
>
> Installation Directory: [/opt/shibboleth-idp] ?
> /home/rdw/idp

So it would seem that /opt/shibboleth-idp has the relics of a previous install.  Remove it entirely before you start.

Also, and this may be where the subsequent confusion lies - run the install(or the update) from inside the unpacked distribution.
If you run from within your distribution things are going to get very weird.
