Remove a previously deselected package to install postgres?

Question

---

So I was meant to run

add-apt-repository ppa:pitti/postgresql
apt-get update
apt-get install postgresql libpq-dev

but instead I ran without the previous two commands

apt-get install postgresql libpq-dev

which I then followed with:

apt-get --purge remove postgres
apt-get auto-remove

and tried to start back up properly from the first step however, my machine is still installing postgres 8.4 instead of 9.2.

How can I get it to stop doing that?

Edit: I see that the package is not being fetched...

W: Failed to fetch http://ppa.launchpad.net/pitt/postgresql/ubuntu/dists/lucid/main/binary-i386/Packages.gz  404  Not Found

May be a server error that just happens to be live the first time I try to install it.

Edit 2: Turns out that it is using "pitt" instead of "pitta" for some reason...will completely restart. ARGHH.

Edit 3: pitti not pitta

Answer 1

The package you are searching for is postgresql-9.2 not potgresql according to the ppa you are using.

sudo add-apt-repository ppa:pitti/postgresql
sudo apt-get update
sudo apt-get install postgresql-9.2 libpq-dev
