Bristol mirror GPG problem ubuntu repository

Hello,

I am getting a GPG error with the ubuntu repository at the bristol UK
mirror.

When my source.list has this line:

deb http://www.stats.bris.ac.uk/R/bin/linux/ubuntu/ intrepid/

On an "apt-get update" you get this:

W: GPG error: http://www.stats.bris.ac.uk intrepid/ Release: The
following signatures were invalid: BADSIG D67FC6EAE2A11821 Vincent
Goulet <vincent.goulet at act.ulaval.ca>

Whereas if I use another mirror e.g.:

deb http://cran.cnr.berkeley.edu/bin/linux/ubuntu/ intrepid/

I don't get such an error.

It could be a problem this end but I think it is more likely that
something is going wrong with the GPG signing at bristol.

Dan
