For the SemWeb installation contest I was looking on the web for a simple way to install Virtuoso on my virtualized Ubuntu server 9.10 It seems that kubuntu guys are very excited about semantic web & desktop [http://www.kubuntu.org/news/kde-sc-4.4-rc-2] and their interest come from this application [http://nepomuk.semanticdesktop.org/xwiki/bin/view/Main1/]. just few lines: {{{ sudo aptitude install python-software-properties sudo add-apt-repository ppa:kubuntu-ppa/beta sudo aptitude install virtuoso-server }}}
