Hi Annie,

Thanks for reporting this. I wasn't able to recreate the issue that you
hit. Here are my results: https://paste.ubuntu.com/p/wN5Z6txBxn/.

Is there anything different in your environment that you're aware of?
Following are the contents of the postinst script. If you're still able
to recreate this and can these commands manually you may find which
command is failing.

For now I'm going to mark this as Incomplete until we can get more
details for how to recreate.

Thanks,
Corey

Title:
  dpkg eror processing package nova-compute

Status in OpenStack Compute (nova):
  Invalid
Status in nova package in Ubuntu:
  Incomplete

Bug description:
  Hello! 
  I've encountered the bug while installing Nova on compute nodes:

  ...

  Setting up qemu-kvm (1:2.11+dfsg-1ubuntu5~cloud0) ...

  dpkg: dependency problems prevent configuration of nova-compute-kvm:
   nova-compute-kvm depends on nova-compute-libvirt (= 2:17.0.1-0ubuntu1~cloud0); however:
    Package nova-compute-libvirt is not configured yet.

  Errors were encountered while processing:
   nova-compute-libvirt
   nova-compute-kvm
  ...

  Installation failed when executing 'post-installation script'. 
  After some investigation I've found out that if I've create 'nova' user BEFORE running package installation, it's will be succeded. 

  Steps to reproduce
  ------------------
  1. Prepare the node for installing nova-compute packages
  2. Run 'apt-get install nova-compute'

  Expected result
  ------------------
  Nova-compute installed successfully without errors

  Actual result
  ------------------
  Installation failed with dpkg error

  Workaround
  ------------------
  1. Create system user: add to /etc/passwd
     nova:x:64060:64060::/var/lib/nova:/bin/false
  2. Create system group: add to /etc/group
     nova:x:64060:
  3. Run 'apt-get install nova-compute'
     
  My Environment
  ------------------
  Ubuntu 16.04.4 LTS, 4.4.0-116-generic
  Openstack Queens Release
  Nova 17.0.1-0ubuntu1
