Upgrading Debian Etch Machines to Lenny

Step-1
First set your /etc/apt/sources.list to point to Lenny repositories:

deb http://ftp.gb.debian.org/debian/ lenny main contrib non-free
deb-src http://ftp.gb.debian.org/debian/ lenny main contrib non-free
deb http://security.debian.org/ lenny/updates main contrib non-free



Step-2 Update your local cache and get the latest apt, aptitude and dpkg versions. # aptitude update # aptitude install apt dpkg aptitude
Step-3 Perform a full-upgrade, which will finally update your machine from Etch to Lenny. # aptitude full-upgrade

Apt GPG Key Installation

gpg --keyserver subkeys.pgp.net --recv-keys xyxyxyxyxy

apt-get update

W: GPG error: http://ftp.de.debian.org lenny Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD55BE302B NO_PUBKEY 4D270DEDB40584E6

Stuttgart into a lecture-hall of 300, already fully packed some 15 minutes before start.

Can an Eagle that Flies also Swim?

As soon as it was made known the lecture was on Linguistics, I lost hope of taking much back, but Noam's opening example grabbed my attention.  Notice the sentence..

Can an eagle that flies also swim?
This is a perfectly simple sentence at first look, but our implicit knowledge of the eagle's primary ability to fly is note-worthy.  Wouldn't we understand this sentence differently if we knew of a species of eagles that also swam?

Some other provocative thoughts...
