This isn't a bug -- we're blocking packages in wily-proposed
specifically because they can be slightly broken, and the tests that
failed and currently block promotion of the package are meant to do just
that -- block things that may be a little buggy. From there, partial
upgrades make things even worse, since you may be missing important part
of underlying libraries.
IN this case, a partial upgrade of NM is obviously slightly wrong. I
don't know how you got to that state, but my guess is that you have the
proposed repository enabled, something that is explicitly strongly
discouraged on wily unless you really know what you're doing. I believe
dino99 exposes it quite well -- partial upgrades would break things, and
the packages have remained in proposed for that reason (regardless of
block-proposed, which wouldn't stop you in getting out of your way to
upgrade the packages manually).
I've just done an upgrade using wily-proposed here, of network-manager,
and it more or less works appropriately when all the packages are
installed.
For reference, the way to upgrade NetworkManager is the following:
sudo apt-get install -t wily-proposed network-manager libnm0 libnm-glib4
libnm-util2 gir1.2-networkmanager-1.0
network-manager-gnome (nm-applet) and the libnm-gtk* libraries *do not*
always need to follow, they should (and appear to) still work just fine.
In the same vein, to downgrade back to network-manager versions that are
in wily-release, first check the version available via 'apt-cache policy
network-manager' from wily/main:
network-manager:
Installed: 1.0.4-0ubuntu3
Candidate: 1.0.4-0ubuntu3
Version table:
*** 1.0.4-0ubuntu3 0
100 /var/lib/dpkg/status
1.0.4-0ubuntu2 0
99 http://ca.archive.ubuntu.com/ubuntu/ wily-proposed/main amd64
Packages
0.9.10.0-4ubuntu23 0
500 http://ca.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages
(from my own system right now) the value for wily/main is
0.9.10.0-4ubuntu23.
sudo apt-get install network-manager=0.9.10.0-4ubuntu23
libnm0=0.9.10.0-4ubuntu23 libnm-glib4=0.9.10.0-4ubuntu23 libnm-
util2=0.9.10.0-4ubuntu23 gir1.2-networkmanager-1.0=0.9.10.0-4ubuntu23
Here to downgrade back, I also needed to add 'network-manager-dbg-
libnm0-' to the above line, because for this particular upgrade, NM 1.0
adds a new libnm0 package, and I also had network-manager-dbg installed.
This will force them to be removed.
