Received 3.2.21-1ubuntu1.1 versions of libnl* with upgrade about a day ago, even though definitely have "proposed" repository turned off. This cause network-manager to fail after boot, as described.
Then upgraded again when internet connection restored. This re upgraded the libnl* packages to the 3.2.21-1ubuntu1.1 versions again, but also upgraded network-manager to 0.9.8.8-0ubuntu7.3 (it was previously vrs. 7.2). Everything works again with these versions.
