Check program / OS documentations packaged with the application to see if the answer is there, using the information packaged above. If it's a GUI application, simply go to the Help menu.
You can often find README docs in the application directories.
Some programs have websites and documentation. Google under the program name; if it's open source, they're often in places like Sourceforge so if you see a web search hit for your program there, try it first. These sites often have user/development team forums: If the program is commercial, the vendor name will probably locate them. Use the internal search at these places before asking for help, someone may already have posted a fix or workaround.
You can also try:
- groups.google.com to find mailing lists if you can't find what you're looking for via web search.
- Linux Documentation Project. "Man" and how-to files describing the OS and its aspects, information on specific applications, and how-to guides (like setting up a wireless system or a laptop)
- Debian packages site. Here, you can find information about a Debian-distributed package, including a bug listing.
