I ran:

%> sudo add-apt-repository ppa:chris-lea/zeromq
%> sudo aptitude update
%> sudo aptitude install zeromq3 php-zeromq # result: zeromq3 - no such package found

I tried restarting my system, running sudo apt-get update, restarting again, but in all cases I get the same package not found result.

I have verified that these packages exist for 12.04 by filtering for Precise from the "Published in:" dropdown at the page.

What do?

ZeroMQ3 cannot be installed with a single zeromq3 package. I don't know why. You can still install ZeroMQ3 with 3 packages (libzmq3-dbg, libzmq3-dev and libzmq3) separately. So the complete solution is:

sudo add-apt-repository ppa:chris-lea/zeromq
sudo apt-get update
sudo apt-get install libzmq3-dbg libzmq3-dev libzmq3

How to know these packages are libzmq3-dbg, libzmq3-dev and libzmq3? You can go to and click View package details, then click the package you desired. You'll see them in Built packages section.
