AttributeError: 'str' object has no attribute 'register_opts' when upgrading

[Iain Lane]

Hi there,

nova-common 2012.2~f1~20120503.13935-0ubuntu1 fails to upgrade (in this case from 2012.1-0ubuntu2.1).

I added set -x to the top of the postinst so we can see what's going on:

laney@raleigh> sudo dpkg --configure --pending ~
Setting up nova-common (2012.2~f2~20120531.14249-0ubuntu2) ...
+ [ configure = configure ]
+ getent group nova

+ [ nova = nogroup ]

dpkg: dependency problems prevent configuration of nova-network:
 nova-network depends on nova-common (= 2012.2~f2~20120531.14249-0ubuntu2); however:
  Package nova-common is not configured yet.
dpkg: error processing nova-network (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:

Unfortunately the conversion tool doesn't mention which line it's having problems on.

Cheers.
