I have a VPS that has Ubuntu 11.10 on it. Unfortunately, only the 11.10 Desktop (not server) image was available as an image to install your VPS with. How can I remove the packages included in the Desktop install, and, if needed, install the packages that only the server install has?
sudo apt-get remove ubuntu-desktop and then
sudo apt-get autoremove. Unfortunately, that didn't work: it only removed 'libjudy-debian' (or something like that) which was installed from having 'miredo' installed at one point.
