All reports of distribution-and-experimental-mismatch for the archive. The extended description of this tag is:
The Distribution in the .changes file indicates that packages should be installed into a non-experimental distribution (suite), but the distribution in the Changes field copied from debian/changelog indicates that experimental was intended.
This is an easy mistake to make when invoking "sbuild ... foo.dsc". Double-check the -d option if using sbuild in this way.
