Some time ago Rails 2.2 was released. Since than the framework requires rubygems 1.3.1 to run. Unfortunately Ubuntu 8.10 only has rubygems 1.2.0 in its repositories. A quick google search didn’t yield a good solution for this. Everyone is suggesting to install the vanilla rubygems-1.3.1.tgz, but I feel more comfortable having rubygems managed by Ubuntu’s package manager. So I created the package myself.
It’s now available from my PPA. To install it you need to add the following lines to your /etc/apt/sources.list file:
deb http://ppa.launchpad.net/maciejb/ppa/ubuntu intrepid main deb-src http://ppa.launchpad.net/maciejb/ppa/ubuntu intrepid main
For further instructions please follow this link. My PPA’s address is: https://launchpad.net/~maciejb/+archive/ppa.
Update (2009/09/08): Brightbox currently has the most up-to-date Rubygems repository available: http://wiki.brightbox.co.uk/docs:brightboxaptrepository
