TRI Import.ps1 fails for websites-only

Question

I am trying to import the SDL Tridion Reference Implementation using the supplied import.ps1 power-shell script but getting the following error indicating something amiss with default templates.

I've tried with

.\import.ps1 -cmsUrl "http://cms.tri.com/" -importType "all-publications"

and

.\import.ps1 -cmsUrl "http://cms.tri.com/" -importType "website-only"

I did note that the documentation states to create 000 Empty Master when the content port packages expect 000 Empty - needless to say I've got both whilst I try to get this to work!

I've removed any Inherit from Parent checked values on the Page Template in case this was affecting it.

I did manage to import the 100 Master.

I've also confirmed that I'm able to manually create a dummy page in the 400 Example Site Publication.

Update

I've run with debug on and can see this fails at:

2015/05/01 00:42:59 <72> [Debug] Going to save item tcm:0-0-0 with data:

To this end I've ensure that

/webdav/400%20Example%20Site/Building%20Blocks/Modules/Core/Editor/Templates/Content%20Page.tptcmp

1. exists
2. that I am able to create a page with the same
3. I can set a SG manually with this as the degault
4. I can create a page with this set as default

Answer 1

So I delved a little further a followed what the code was doing.

The devil was in the detail

<tcm:DefaultPageTemplate IsInherited="true" blah blah blah />

So as I'd implemented this into an existing Blueprint for testing I'd neglected to consider that the SG 'Home' was created above the 100 Master and therefore didn't have access to the necessary Page Template to be set so it could inherit.

Solution: Localize Home at the 100 Master and set the Default Page Template to Content.

Tested I could then do this manually at the 400 Example Website level and executed the script again.

BOOM. Success.

Now looking forward to some real fun.

Note on the setup

Note also that the documentation does assume this is on a clean install - which MINE WASN'T ... so most of this pain could be considered self-inflicted but I hope it's still usefull to those that want to have it as part of a wider sales pitch-set etc.
