As I continue to configure my server I keep coming across sites that say to use add-apt-repository and I had used it before on my 10.04 server. I updated my server to 12.04 (fresh install) recently, and when add-apt-repository doesn't appear to be installed on my machine. I tried googling for it and I couldn't find anyone else with the same problem so I imagine that it just didn't get installed correctly either because of a screwed up DVD or because something goofed on install. My question is what repository/package is this supposed to be in? I was wondering if I can manually install something to get it. And if there isn't where can I find the official binary for add-apt-repository for 12.04? I can just add it to the bin myself if I can download it.
This install is 12.04 Ubuntu Server x64 on a old Pentium D machine.
