Hi
I am using a distro that is called Bio-Linux based on Ubuntu 10.04 LTS 64 bit
I get this error massage in the update manager:

"W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://www.stats.bris.ac.uk lucid/ Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 51716619E084DAB9

W: Failed to fetch http://debian.scribus.net/debian/dists/lucid/Release Unable to find expected entry non-free/binary-amd64/Packages in Meta-index file (malformed Release file?)

W: Failed to fetch http://www.stats.bris.ac.uk/R/bin/linux/ubuntu/lucid/Release

W: Failed to fetch http://debian.tagancha.org/debian/dists/lucid/Release Unable to find expected entry non-free/binary-amd64/Packages in Meta-index file (malformed Release file?)

W: Some index files failed to download, they have been ignored, or old ones used instead."
please advise how resolve this error massage either by removing these addresses from wherever they are stored, or by fixing the connection.
Thank you
