PPA download doesn't work?

Sorry, I'm pretty new, but I followed instructions to get the bitcoin software from the PPA:

sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update

(both completed OK, but then)

sudo apt-get install bitcoin

any ideas?  Are we just waiting on Matt Corallo?

I have my own question pertaining to this - a block is created every 10 minutes with a reward of 25BTC, so that makes 3,600 BTC every 24hrs. That to me indicates that punters are injecting 3,600 x ~$800 dollars (or CNY, JPY EUR equivalant) = ~ $3m daily into the BTC exchange network every day - by miners selling their newly-minted BTC. For BTC to maintain its price, there has to be that level of investment every day (until the block reward halves again in April 2017). Unless, of course, miners start buying real stuff with their BTC. Either way, I don't see how we can be sure that this level of investment will necessarily keep going (of course, it might go up, but every time it goes up, it requires more every day to keep it going at that level.)  Suppose the price rose to $10,000. Then that would need $36m daily investment. Unless the miners are actually only selling a fraction of their mined coins. But then they wouldn't be able to cash in on their spare coins without significantly depressing the price... Had Bitcoin "taken off" later on in the supply process, say when block reward was 6.25 or 3.125BTC the amount of fiat support needed would have been less.  Has it therefore "grown too quickly"?

Someone suggested that Palestine might adopt BTC as a currency - but a commenter replied that Palestine has serious problems with internet coverage. There exists an opportunity therefore for someone to design a crypto-currency that might work in those conditions - maybe it might use the mobile phone network to assist with block chain verfication, or something completely different. Might catch on in parts of Africa, too?  Innovative enough???

Surely "adjusting supply" can be done by BTC holders themselves. Isn't that the whole point?

I'll put it more directly - it would be a good idea if we all played at being "central bankers", from time to time.

There will other speculative periods, with booms and busts. It's in all our interests to get as many people as possible involved in Bitcoin. When the price is rising "too fast" - there are more people wanting to buy into bitcoin than there are those willing to give up a bit of ownership. So, if "we" attempted to balance demand and supply at these critical moments we might succeed in bringing BTC price swings down below bthe critical threshold where a speculative frenzy ensues, thus ensuring a more smooth rate of appreciation - and hence BTC adoption.

In this respect "selling high, then buying low" is just a method of stabilising the currency's value.

Or, to put it another way, strict hoarders may benefit by strategic selling. Would it be possible to coordinate this? Or have some method of knowing how much is going on? No - any such information would act against the market-makers. But we could have an indication of how much market manipulation might be appropriate. Then each of us decide how much to act based on our oown holdings. Most bitcoins are, apparently, held by accounts with less than 500BTC in them, so if a lot of us acted in this way, it would have a noticable effect...

Earlier in this topic someone suggested an appreciation of less "than 5% per annum against another major currency" (basket) would be desirable. Now that seems to me to be trying to make Bitcoin like any other currency.... I would have thought that appreciation of 3 times per annum would be quite acceptable - giving appreciation of an order of magnitude (ie x10) every two years. That seems to me to be quite reasonable with a growing BTC-based economy.
