I use Ubuntu 12.04 64-bit, I did the following: sudo gedit /etc/apt/apt.conf and added  APT::Install-Recommends "false"; APT::Install-Suggests "false";    But it did not work. When I try to install a package, it still wants to install the suggested and recommended packages. How can I solve this?

The whole update process seems somewhat confusing to me.  I can understand the need to run sudo apt-get update prior to installing another package, but, what is the difference in running update from the command-line and using the Synaptic package manager for updates and/or the the Auto-updater.  If there is no difference, why do we have all three?

Installing Deb packages on the command line, using dpkg -i, only installs the package in question and displays errors of unresolved dependencies (manually solved by apt-geting the packages it complains about). How do I automatically resolve dependencies when installing standalone packages?
