apt-get update may give you the following error
I'm not yet sure, the following is supposed to work ,but it didnt.
The downside is that it will often by dependency turn into yet another apt-get upgrade. But thats what we came for, right?
Documentation seems to exist at:http://wiki.debian.org/SecureApt
One thing which can cause you to get stuck real bad here:
The keyring stuff uses GNUtls.
GNUtls doesn't read the apt proxy setitngs!
GNUtls doesn't read $HTTP_PROXY
GNUtls doesn't read $HTTPS_PROXY.
It only reads $http_proxy and $https_proxy !!!
Try adjusting that and...
