Complete Guide to the Synaptic Package Manager

Please do not post links to other tutorials unless you are responding to specific issues. There are many helpful walk-throughs available that do not need reposted or linked here. The walk-throughs you see in the Tutorials & Guides categories are step by step directions that user's of the forum have actually done to get software/hardware to work. Normally with modifications to the guide, if they used one, they followed in order to make it work on Zorin.

Please feel free to rewrite this write-up, but please include other options, maybe AppGrid or the benefits of searching the web, that make it specific to Zorin or the issues that you may face when using/installing on this OS.
