I've tried LyX Version 2.0.6 from Software Center and 2.0.7 from 3rd party PPA. In both versions, clicking the view button to create a PDF does nothing. There is no error shown, it just has no effect.
UPDATE
I can go to document -> settings -> output and choose "DVI" as the format. The button now does something but still does not work right.
First it says:
No information for converting png format files to eps.
Define a converter in the preferences.
Then it says:
LaTeX Error: File prettyref.sty not found
UPDATE 2
I have found this file, which might be prettyref.sty:
%%

%% generated with the docstrip utility.

%% End of file `prettyref.sty'.
No idea what to do with it though. locate *.sty has tons of paths.
UPDATE 3
I have created /usr/share/texmf/tex/latex/lyx/prettyref.sty and placed the above contents in it. I then ran sudo texhash. Now the error is that it can't find ulem.sty! This is going to be miserable, having to track down all these missing files!
