I am new to lyx. I installed version 1.6.5 on Ubuntu 8.04 Linux, then opened the tutorial.When I tried to view the Tutorial as DVI, I got the following message for each of several .png objects in the document:
An error occurred whilst running python -tt '/usr/local/share/lyx/lyx2lyx/lyx2lyx'
Warning: Invalid LyX file. Warning: Quiting. Error: Cannot convert file What should I do? Dean
