I am not using kde desktop enviroment(lxde instead), and I download
apt-get install kchmviewer. It downloaded a lot of packages and takes up space about
200M. However when I uninstall the packages via
sudo apt-get --purge autoremove kchmviewer it doesn't remove the packages installed alongside the install. It only removes hundreds of
kb. I think I did right way, usually
--purge autoremove will remove all the packages alongside the install, but not this case.
How can I remove all the package that actually I don't need, it is annoying to have them installed but can't remove them.
