maas metapackage allows a package version number mismatch

[Chris Johnston]

Upgrading MAAS by doing 'apt-get install' maas results in mismatched package versions.

ubuntu@maas:~⟫ apt-cache policy maas
maas:
  Installed: 1.5.4+bzr2294-0ubuntu1.2

ubuntu@maas:~⟫ apt-cache policy python-maas-provisioningserver
python-maas-provisioningserver:
  Installed: 1.5.4+bzr2294-0ubuntu1.2

Now add the testing PPA and install the new version of MAAS:

ubuntu@maas:~⟫ sudo apt-get install maas

If you install python-maas-provisioning server instead, it will properly upgrade all of the packages:

ubuntu@maas:~⟫ sudo apt-get install python-maas-provisioningserver

The following packages were automatically installed and are no longer required:
  avahi-daemon avahi-utils erlang-asn1 erlang-base erlang-corba erlang-crypto

  erlang-ic erlang-inets erlang-mnesia erlang-nox erlang-odbc erlang-os-mon

  libavahi-common3 libavahi-core7 libdaemon0 libnss-mdns libodbc1 libsctp1
  lksctp-tools pwgen python-amqplib python-oops-amqp python-txlongpoll
  rabbitmq-server
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:

The following NEW packages will be installed:
  maas-proxy

  maas-region-controller maas-region-controller-min python-django-maas
  python-maas-client python-maas-provisioningserver

Since you can install MAAS initially by running 'apt-get install maas' you should also be able to upgrade maas the same way.

It seems fixed now with 1.7.1.
