I upgraded my daughter's desktop to squeeze, and the last step was to install Trinity. Unfortunately, the trinitydesktop.org site is not found in iceweasel, and when I tried to download the key for the repository, I get:

# apt-key adv --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /etc/apt/secring.gpg --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0
gpg: requesting key 2B8638D0 from hkp server keyserver.quickbuild.pearsoncomputing.net
gpgkeys: HTTP fetch error 7: couldn't connect to host
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Is there a problem on the site or is it local network problem?

Thanks,
