Comment 28 for bug 1423151

I would like to test this out (I really need afs badly), but I am not sure how do it. I followed the dirextins at https://wiki.ubuntu.com/Testing/EnableProposed, i.e.,

Added to /etc/apt/sources.list:

deb http://archive.ubuntu.com/ubuntu trusty-proposed restricted main multiverse universe

Created the file /etc/apt/preferences.d/proposed-updates with:

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

And tried to do an upgrade. Not sure what package to upgrade. For example, I tried:

sudo apt-get install openafs-modules-dkms/trusty-proposed
sudo apt-get install openafs-client/trusty-proposed

and some others and they all report:

E: Release 'trusty-proposed' for 'openafs-modules-dkms' was not found

How do I proceed?
