[ubuntu-uk] truetype fonts on Edgy

[baz]

I'm trying to install M S true type fonts on Edgy but when I type,
 sudo apt-get install msttcorefonts

I get,
Package msttcorefonts 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 msttcorefonts has no installation candidate

Where am I going wrong here?
