Trying to update 11.04 to 11.10, I get this:
Failed to fetch http://pt.archive.ubuntu.com/ubuntu/pool/universe/g/gmp4/libgmp3c2_4.3.2+dfsg-2ubuntu1_amd64.deb 403 Forbidden
Going to the URL in the browser, I see that "gmp4" seems to be empty, trying the same URL for es.archive.ubuntu (for example) has no problem.
Any ideas?
