How to upgrade lcov if you already have one in ubuntu?

I have lcov installed on my ubuntu 10.1. My lcov version is 1.8, how do I upgrade to the latest ver开发者_如何学Pythonsion, which is 1.9?

I just installed the .deb from Natty: http://packages.ubuntu.com/natty/lcov

Download and install it with:

wget http://mirrors.us.kernel.org/ubuntu//pool/universe/l/lcov/lcov_1.9-2_all.deb
sudo dpkg -i lcov_1.9-2_all.deb

I did this on 10.04 LTS without any dependency-issues.
