Bug description:
[Impact]
Hello!
I've encountered the bug while installing Nova on compute nodes:
...
Setting up qemu-system-x86 (1:2.11+dfsg-1ubuntu5~cloud0) ...
Setting up qemu-kvm (1:2.11+dfsg-1ubuntu5~cloud0) ...
Setting up qemu-utils (1:2.11+dfsg-1ubuntu5~cloud0) ...
Setting up python-keystone (2:13.0.0-0ubuntu1~cloud0) ...
Processing triggers for initramfs-tools (0.122ubuntu8.11) ...
update-initramfs: Generating /boot/initrd.img-4.4.0-116-generic
Setting up nova-compute-libvirt (2:17.0.1-0ubuntu1~cloud0) ...
adduser: The user `nova' does not exist.
dpkg: error processing package nova-compute-libvirt (--configure):
subprocess installed post-installation script returned error exit status 1
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.
dpkg: error processing package nova-compute-kvm (--configure):
dependency problems - leaving unconfigured
Setting up python-os-brick (2.3.0-0ubuntu1~cloud0) ...
No apport report written because the error message indicates its a followup error from a previous failure.
Setting up python-nova (2:17.0.1-0ubuntu1~cloud0) ...
Setting up nova-common (2:17.0.1-0ubuntu1~cloud0) ...
Setting up nova-compute (2:17.0.1-0ubuntu1~cloud0) ...
Processing triggers for libc-bin (2.23-0ubuntu10) ...
Processing triggers for systemd (229-4ubuntu21.2) ...
Processing triggers for ureadahead (0.100.0-19) ...
Processing triggers for dbus (1.10.6-1ubuntu3.3) ...
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.
[Test Case]
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
[Regression Potential]
Should be very low. This is a very minor dependency chain to prevent a dependency circular loop.
