Opera Listed in Add/Remove, but not Synaptic

[floborg]

Under 3rd-party apps in Add/Remove, Opera is listed. There is absolutely no description available there. The only indication that it is the Opera browser is the familiar red O icon.

I can't find this package anywhere in Synaptic. I've also searched with aptitude. Nothing.

How can I find out what this package is and it's dependencies, etc.? Here's my list of sources:

deb http://us.archive.ubuntu.com/ubuntu/ hardy main restricted

deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates main restricted

I know. Thanks. I want to understand where the listing in Add/Remove comes from.
