Public bug reported: This is similar to bug 874343, but I was able to fix that one on my own (it was fixed by removing some ruby 1.9.2 packages). The story is that I just upgrade to 11.10, but ran in to a problem during the upgrade: a bunch of ruby packages refused to install. I cleaned up and finished the installation otherwise, and removed the offending packages to get to the root of the problem. If I try to install the 'ruby' package I now get:
