Ok, I tried to avoid asking this question here, as it's noobish and and always closed/downvoted, but I cannot figure it out myself.
I'm on 14.04 and trying to update GNOME from 3.10 to 3.12. Most blogs and such link to this PPA. But I cannot figure out how. I added the PPA, I updated the list of repos but still the 3.12 is nowhere to be found.
How can I do it? I ran out of ideas...
