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

Yeah you can install it by just

sudo apt-get install mercurial

but for me it gave very old version (2.0.2). You can check this by hg version. To get the newer version you can do

sudo apt-get install python-setuptools python-dev build-essential
sudo easy_install -U mercurial

Now I have 3.0.1 version

aniket@ubuntu:~$ hg version
Mercurial Distributed SCM (version 3.0.1)
(see http://mercurial.selenic.com for more information)
