Is Bitcoin core V.0.9 not updated on PPA ppa:bitcoin/bitcoin? Version 0.9 of Bitcoin-Qt just came out. When will ppa:bitcoin/bitcoin be updated? In the meanwhile, any steps showing how to upgrade are welcome!
The PPA is on 0.8.6, which is very recent (just missing 0.9, but I'm gonna hopefully upload that today). What you're referring to is the Ubuntu package distribution, which is very, very, very out of date (to the point of it being largely non-functional).
