Problem with courier in the "Set Up Ubuntu-Server 6.10 how to"

[Freak Willie]

Hi there, everyone. I was doing the "Set Up Ubuntu-Server 6.10 As A Firewall/Gateway For Your Small Business Environment" how to and then in the first step of the third page where I should apt-get the courier-authlib-mysql. When I do this I get a message that says that this package isn't available but got references by other package. I tried to dowload it myself and install but it got dependences that got dependences themself. So I thought the mistake can be somewhere else since that how to is very simple. I shouldn't be getting this mistake. Any idea of what could be happening? Oh, apologizes for my english and my linux knowledge, I'm either a starter in linux and not english mother-languaged.

Thanks anyone.

What's the exact error message you get?
What's in your /etc/apt/sources.list?

Well, since the error message is wrote in portugues I can't just copy and paste it, so I'll try to translate it. I'm getting a message like this:

Reading Package List... Ready
Building Dependency Tree... Ready
The courier-authlib-mysql isn't available, but is referenced by another package.
This may means that the package is missing, got obsolete or is available only through another source
E: The courier-authlib-mysql hasn't instalation candidates

The universe repository is active, so that shouldn't be the problem.
Can you run

apt-get update

and try to install that package again?

Hi, there.

I tried it, but didn't work. I was using ubuntu 6.06 server, so I realized it could be the reason of the error, since the tutorial was wrote for the 6.10 release, I installed the 6.10 (edgy) on the machine and apparently it all went ok apt-getting the files.
