Comment 17 for bug 1251193

Thank you for test JH Park

Here is the way to test I have been through
I followed the guide line of
https://wiki.ubuntu.com/Testing/EnableProposed

* enabling the "trusty-proposed" at the software & update
* sudo gedit /etc/apt/preferences

Package: *
Pin: release a=trusty-proposed
Pin-Priority: 400

* sudo apt-get update;sudo apt-get upgrade -s
* sudo aptitude -t trusty-proposed

of course , I have failed to upgrade by both of them due to dependency
sudo apt-get update; sudo apt-get upgrade
and
sudo apt-get update;sudo apt-get dist-upgrade

please leave me a comment, If I did wrong process
