Hello everyone. Another random post over here rather than ubuntuforums. 
I did a Google search and couldn't find out how to upgrade Kubuntu to the latest dev release (it's easy with Ubuntu, just $ update-manager -d).
I eventually found kubuntu-do-release-upgrade, but that didn't work. Instead I had to use
$ sudo do-release-upgrade -f kde -d
This worked perfectly.
