I need the original released 10.04 server AMD64... This seems to be GONE from the Internet... Any ideas?
Well, I'm assuming you're an iso collector so you need specifically 10.04. :)
You could search for torrent files outside ubuntu domains. I can't post some torrent sites that have it because they contain some warez as well, but doing a little search for the first 3 pages, you're going to find a torrent with enough seeders.
Beware though that you should check the iso's checksum to avoid problems.
