I ran into this today. I was surprised that the update-alternatives support for ruby had been yanked. Here's how to set ruby2.0 to be the default:
sudo ln -sf /usr/bin/ruby2.0 /usr/bin/ruby sudo ln -sf /usr/bin/gem2.0 /usr/bin/gem No promises this will work 100% or not cause problems with other installed ruby dependent software. ruby -v should produce: ruby 2.0.0p384 (2014-01-12) [x86_64-linux-gnu] gem -v should produce: 1.8.23 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310292 Title: installing `ruby2.0` results in ruby 1.9.3-p484 as default version To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ruby2.0/+bug/1310292/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
