[clug-talk] installing clamav on Knoppix

[Carl]

I'm trying to run the clamav virus scanner on a computer that I booted
with a Knoppix 3.8 Live CD.

clamav is not included on Knoppix 3.8 so I'm trying to install using the
command:

sudo apt-get install clamav

But the command returns with:

Reading Package Lists...
Building Dependency Tree...
Package clamav is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package clamav has no installation candidate

I'm not familiar with apt-get as I'm primarily a Fedora Core user. Why
isn't clamav available? Am I doing something incorrect?

Thanks,

Carl
