Problems with Dapper update servers? (Ubuntu 6.04)

[Eric Dunbar]

Hi all, I tried updating my install of Dapper [1] (Ubuntu 6.04) and am
getting 404s (file not found) on the server.

Is there a problem with the servers? Or, is the problem on my end?
Perhaps in the /etc/atp/sources.list?

[1] it's been a week or two since I did the last update so there
should be many updates awaiting me (I wouldn't mind it if Nautilus has
been fixed... right now the desktop image isn't being displayed
properly).

PS Here's the output of apt-get update...
