Comment 5 for bug 1306215

Hi Luis,
I've tried to use the -proposed branch, however it fails to find the new kernel.
Here's a summary of the steps we've taken:

At the end of /etc/apt/sources.list this line was added:
deb http://archive.ubuntu.com/ubuntu/ trusty-proposed restricted main multiverse universe

root@ubuntu14-3:~# cat /etc/apt/preferences
