Hello I am not even sure which trinity version I have installed but it must be a couple of years old (still running Kubuntu 10.04). I would like to purge it before try to install 3.5.13 However Sudo dpkg -l | grep trinity does not show anything sudo dpkg -l | grep kubutu-desktop Show kubuntu-desktop-kde3 1:10 Any advice how to proceed? thanks Uwe Brauer
