SharePoint 2010: Failed to create sample data when running the wizard after installing the language pack

Question

I install the Spanish lang package on SP 2010 and the Wizard, which starts after installation, gives the error “failed to create sample data”, plus this stack:

02/11/2011 11:31:59  14  ERR                      Exception: System.NullReferenceException: Object reference not set to an instance of an object.

   at Microsoft.SharePoint.PostSetupConfiguration.EvalModeProvisionTask.EvalProvision()
   at Microsoft.SharePoint.PostSetupConfiguration.EvalModeProvisionTask.Run()
   at Microsoft.SharePoint.PostSetupConfiguration.TaskThread.ExecuteTask()

I looked for this problem, tried a couple of recipes, but no luck. Ideas really appreciated, thanks!

Answer 1

The workaround is to create the root site collection on port 80. Thus, the wizard completes successfully.
