Bug Description
Setting up an os-ansible-
This is happening regardless of the kernel (tested with 3.13, 3.16 and 3.19) on a fresh VM with no specific customization.
Order of steps to reproduce:
1) launch image from ubuntu cloud catalog
2) apt-get diet-upgrade
3) apt-get install git linux-image-
4) git clone https:/
5) cd os-ansible-
6) git checkout kilo
7) ./scripts/
8) ./scripts/
This appears to be harmless as the deployment eventually succeeds.
Here is a brief extract of the traces:
