I have already posted two ways of installing QQ on Linux. However, for the less experienced in the ways of Linux, here is an alternative that works okay- a simple chat- all your contacts will turn up as well.

Go to terminal and enter these three command lines, in order to use Pidgin QQ.

sudo add-apt-repository ppa:lainme/pidgin-lwqq
sudo apt-get update
sudo apt-get install pidgin-lwqq libpurple0

For those who wish to continue wallowing in Windoze filth, just ignore this post.

Note that this is for Ubuntu-Mint and Debian based distros.
