[how to purge 3.5.11] (was: [trinity-users] which trinity version I have installed, purge and install at least 3.513)

Thanks I found out that I am using still 3.5.11. How can I purge the complete installation in order to have clean install of 3.5.13? I tried out sudo apt-get purge kubuntu-desktop-kde3 kubuntu-default-setting-kde3 but it does not purge the whole trinity 3.5.11. What was the command I used to install 3.5.11, which had all sort of dependencies. I googled around and could not find any instructions anymore. Uwe BTW, Tim why don't you use pgpmime instead of inline http://josefsson.org/inline-openpgp-considered-harmful.html
