By default, you cannot view CHM file in Ubuntu. To view the CHM file, you can use GnoCHM. However, I found that GnoCHM is not so stable and crash a lot. Hence, another option is to convert it to PDF. What you need is the chm2pdf and python-beautifulsoup packages.
Install the packages
sudo apt-get install chm2pdf python-beautifulsoupConvert the CHM file to PDF
chm2pdf --webpage --beautifulsoup filename.chmYou can even change colour, font, and margin of the generated PDF file. For more information on how to do so, please invoke
man chm2pdfcommand on the terminal.
