When I want to convert a man page to an HTML file on an OS X or Linux system, I pipe the man page file into groff - see Converting a man page to HTML, PDF, text. I've used groff for that purpose on CentOS, but, when I tried that technique today on two Ubuntu Linux systems, I received the same "groff: can't find `DESC' file" error message on both, which was followed by "groff:fatal error: invalid device `html' (try installing the `groff' package?)" Both systems were running 12.04 LTS (Precise Pangolin). I was able to resolve the problem by installing the groff package with apt-get.
