errors when I try to install "medley-package-config" with "apt-get"

[I-1]

Hi,

I am having the following problems when I try to install "medley-package-config" with "apt-get"

See the error message below:

# apt-get install medley-package-config
Reading Package Lists... Done
Building Dependency Tree... Done
Package medley-package-config has no available version, but exists in the database.
This typically means that the package was mentioned in a dependency and
never uploaded, has been obsoleted or is not available with the contents
of sources.list
E: Package medley-package-config has no installation candidate

What am I doing wrong here?

Thanks, I-1
