I have for some time had TDE key problems on my husband's desktop.  I 
keep thinking that it must have been solved by now and trying again.

He has Wheezy with TDE 3.5.13.2, just as I have. I have no problems 
with my own key.

Here is my latest attempt:

root@Nyx:/home/peter# apt-key adv --keyserver 
keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0
Executing: 
gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.pZxq195osY --trustdb-name /etc/apt//trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-stable.gpg --keyring /etc/apt/trusted.gpg.d//pkg-mozilla-archive-keyring.gpg --keyserver 
keyserver.quickbuild.pearsoncomputing.net --recv-keys 2B8638D0
gpg: requesting key 2B8638D0 from hkp server 
keyserver.quickbuild.pearsoncomputing.net
gpg: key 2B8638D0: "QuickBuild Trinity Desktop Environment" not 
changed
gpg: Total number processed: 1
gpg:              unchanged: 1

I copied and pasted the apt-key line from the wiki.

And here is why I think that I have a problem:

root@Nyx:/home/peter# aptitude update > key.txt
W: GPG error: http://ppa.quickbuild.pearsoncomputing.net wheezy 
Release: The 
following signatures couldn't be verified because the public key is 
not 
available: NO_PUBKEY 099723A280479E11
root@Nyx:/home/peter#

And key.txt is here:
http://paste.ubuntu.com/7068342/

I must solve this.  He never banks on line, but even so .....

Any ideas?
