The warning has not gone away with the LTS release of Dapper. The installer stops with an error if it can't reach the security updates during installation. This happens at an inconvient time.
Also, the installer should ask if you are behind a proxy so if you are networked and need to use a http proxy it gets set - and would be very convenient if this proxy were used in several places: Firefox, /etc/apt/apt.conf, /etc/wgetrc, etc. -- non-networked install: warns about security updates in the middle of installation https://launchpad.net/bugs/32816 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
