Step 1: Adding two Personal Package Archives(PPA) to your Ubuntu system
sudo add-apt-repository ppa:mercurial-ppa/releases sudo add-apt-repository ppa:tortoisehg-ppa/releases
Your system will fetch the PPA’s key. This enables your Ubuntu system to verify that the packages in the PPA have not been interfered with since they were built.
Step 2: Now, you should tell your system to pull down the latest list of software from each archive it knows about, including the PPAs you just added
sudo apt-get update
Step 3: you’re ready to start installing software from the PPAs
sudo apt-get install mercurial sudo apt-get install tortoisehg-nautilus
