Correct way to install Mercurial on Ubuntu

Question

I am kind of new to both, Mercurial and Ubuntu.

I seem to have awkwardly installed a few other software packages already, so I wanted to see how others would go about do

Answer 1

If you are using an older version of Ubuntu (12.04 perhaps?), use the Mercurial PPA.

sudo add-apt-repository ppa:mercurial-ppa/releases
sudo apt-get update
sudo apt-get install mercurial

As of this writing, this installs mercurial 3.0.1 on Ubuntu 12.04 for example.
