So, I am trying to install Octopress. I need ruby 1.9.2. It looks like
sudo apt-get install ruby wants to install ruby 1.8. I've read that RVM is a good way to go. But it seems rather excessive since I don't expect to use much else apart from the bare-bones needed for octopress. Do I have an alternative?
I use a TeXlive 2011 I installed myself, but I like being up to date there. For ruby, I literally only want it for Octopress, so I don't really want to have to deal with maintenance separately if I can avoid it. I'd prefer if
sudo apt-get update would deal with it for me.
I know there are PPAs. But the thing is, there are loads of PPAs. How do I choose a trustworthy one?
