Hi,

the full local cache tutorial is here
http://linux.or.ug/node/25

i see 2 solutions to the problem


rm /var/lib/apt/lists/* 

(and wait about 10 minutes to do sudo apt-get update )
is one.
the other one is reinstalling the key:

gpg --keyserver keyserver.ubuntu.com --recv 437D05B5; gpg --export --armor 
437D05B5

sudo apt-key add -; gpg --keyserver keyserver.ubuntu.com --recv 437D05B5; gpg 
--export --armor 437D05B5

(that is 2x1 line) (not sure why this solution uses a shorter key than 
40976EAF437D05B5 if the above doesnt work, try with the long key too)
