Might mean just that the mirrors are not yet up to date...

Seems related to bug #932581

I get similar error when trying to upgrade to 13.04 from 12.10. (amd64)

xpdf is understandable since xpdf,rep-gtk is marked as hold to an older version, but there should not be any problem in openssh,xemacs

Ok held packages can get back with dist-upgrade

open your terminal and type as

sudo apt-get update
sudo apt-get dist-upgrade

dist-updgrade doesn't work.
But I was able to upgrade to raring with do-release-upgrade.
The errors have dispappeared in raring.
