I must correct myself. I DID remove mp-fremantle-205-pr.

I just did a check - I guess I should have done it before posting - and I have no mp-fremantlef* debs anymore..

This is what apt-get tells me:
Package mp-fremantle-203-pr 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 mp-fremantle-203-pr has no installation candidate
