ubuntu minimal build fails with: KeyError: 'blockdev'

[Andreas Scheuring]

Since yesterday the DIB 2.8 ubuntu-minimal build is failing with KeyError: 'blockdev'

I started a fresh xenial vagrant box and did the following:

     apt-get update
     apt-get install -y python-pip qemu-utils kpartx debootstrap curl
     pip install diskimage-builder
     disk-image-create -x -o test ubuntu-minimal vm

This is due to networkx 2.0. changes are in flight to fix this with a pin. please try again with 2.9.0 when it is released shortly

Hello,
I am testing master and it still fails for me:

Steps to reproduce:
disk-image-create -x -o test ubuntu-minimal vm

the output ends like this:

OK, I confirm is fixed. But you have to make sure on the system the version of Networkx is at max 1.11 (not 2.x).

The problem was that the patch of course does not fix a system where networkx was already upgraded ! :)
