TF30272: Template not found on the server

Today I wanted to upload a customized Process Template (based on Conchango's Scrum Process Template) to a clean dual-server Team Foundation Server deployment but it failed throwing the following dialog at my face:

Clicking the link See error log for details I was able to locate the cause of this failure:

An error occurred in the Windows SharePoint Services plug-in that defines the project portal for the team, based on a SharePoint site template but as we can tell from the log file the template was not found found the server (TF30272: Template not found on the server).

The error log does not tell us the name of the template. To find out the name we need to take a look at the Wss.xml file in the process template folder hierarchy and look for the template attribute of the site node:

<site template="Agile Software Development with Scrum" language="1033" />

As can be determined from the Wss.xml file the name of the SharePoint template that will be used for creating new Team Projects based on this Process Template is Agile Software Development with Scrum. I guess I could have expected this error since I haven't yet installed the server-centric components of Scrum for Team System on the application-tier!
