The Trinity LiveCD worked well to install TDE 3.5.13 with Kubuntu Maverick, on a fresh system. Now I wish to upgrade to Trinity with Natty and I'm unsure of the procedure. Should I (add) or (substitute) the four 'Natty' lines to sources.list? Or should I just run <sudo apt-get dist-upgrade> using the Maverick-configured sources.list? Or have I missed (the, some) point? gds, stencil
