apt-get - Package not found problem

[Error1312]

Hi all!

I'm having a problem with apt-get. I'm trying to install aMsn or eterm, so I enter the following command:

apt-get install eterm or apt-get install Eterm

but however I try, it always says: Couldn't find package 'eterm'.
I'm having the same problem with every other package I try to install.

Does anyone has an idea what I should do about this?
