Build failed during RPM installation

Today, I tried to build my own appliance, but the build always fails.
The error log (“details”) does not show any specific reason.

My error log at pastebin:

If you need further information about my appliance, please ask.

Some post scripts failed. Sounds to a temporary issue to me. Did you try again?

… must have been some package.
I created a new appliance with less packages and the build succeeded.

maybe You know which?
I have the same problem

Unfortunately I do not know which package caused trouble.
I created a new “smaller” version with less packages and the build was successfull (I had later issues but that’s another story :smiley: ).
