[Bug 1511735] Re: libnl: fail to bind() netlink sockets

[Ryan Harper]

I've updated the debdiff to include a Breaks:  network-manager (<<
0.9.8.8-0ubuntu7.3) to ensure that users are forced to use the newer
network-manager (ie, this libnl won't install unless user has already
updated their network-manager)   Thanks Mathew for the suggestion.

I've built and tested this in the following way:

1. deploy trusty 14.04
2. apt-get install network-manager
3. download the libnl3 packages (3.2.21-1ubuntu2)
4. dpkg --install libnl-3-200_3.2.21-1ubuntu2_amd64.deb libnl-genl-3-200_3.2.21-1ubuntu2_amd64.deb libnl-route-3-200_3.2.21-1ubuntu2_amd64.deb 

This results in the following (successful blocking of upgrade):

dpkg: regarding libnl-3-200_3.2.21-1ubuntu2_amd64.deb containing libnl-3-200:amd64:
 libnl-3-200:amd64 breaks network-manager (<< 0.9.8.8-0ubuntu7.3)
  network-manager (version 0.9.8.8-0ubuntu7.2) is present and installed.

After installing network-manager 0.9.8.8-0ubuntu7.3, I can successfully re-run the libnl3 install command:

dpkg --install libnl-3-200_3.2.21-1ubuntu2_amd64.deb libnl-genl-3-200_3.2.21-1ubuntu2_amd64.deb libnl-route-3-200_3.2.21-1ubuntu2_amd64.deb
