Question

• GIT
• SVN
• Mercurial

Answer 1

Well, there's:

• git-all which gives you all the git packages [editor's note: do not attempt to install git-all in 16.04 or later, as it breaks with systemd] (or, if you want to get just the core git packages (cli only, as this skips the GUI tool) git-core. See also: Is there a GUI client for Git?
• subversion as for a GUI there are several projects which are designed as a front end to Subversion
• bazaar for a GUI there is bzr-explorer See also: What is Bazaar and how do I use it?
• mercurial and here is a list of Mercurial GUI tools
