Post #17 should get you fixed.
I edited my post to "never mind" because the answer there was already better than mine.
It is a pity that you are re-installing, people here really like it when they go crazy over someone's problem, and then... it works!!
it feels so good!

Thing is, if you reinstall Ubuntu, then try to install Firebird again, there's a good chance you'll just be running into the same problem.
Problems with sources.list are usually easily fixed; it just seems to be time-consuming what with all the back-and-forth (which is what these fora are all about).
I never understand why people get mad with sources.list problems,
just calm down, relax, breath, and analyze the problem,
..is just a list of URLs!!!
Even if you dont have the PGP keys you will be warned several times but it works,
and the URL are the same since first release of Ubuntu,
only change the folder by the current codename.
Did you get a look at the Ubuntu Guide Michael posted a bit earlier?
I think you are trying to run before you learn to walk.
Synaptic is your friend, lots of stuff there to install. Also what is mean as sources.list is the file where the server repositories for all the stuff you want to install is located.
Also you have to remember that some apps you want to install may not be ready for the Ubuntu version you are running, you will get sometimes those weird messages about libraries or broken packages because the app coming from a third party repository or tar ball is not in line with the latest distribution.
In my particular case, all my production equipment uses stables distributions (=a bit old) so Im using currently Ubuntu Server 8.04, Debian Lenny for a mail server and this laptop, and other families laptops use Ubuntu 8.04, sometimes latest version is not for everybody (you may run into problems with video drivers for example or some inestability)
Still have fun and welcome
