Comment 10 for bug 1998168

Hello Jimmy,

It seems that your network rejected HTTP calls to the Internet. This prevented the installer from receiving the list of packages to install (via apt-get update) from the Internet. Presumably, it could be a proxy related issue in your network.

Offline install is an alternative option where packages are only installed from the media/cdrom (this excludes security updates that can only be installed at a later stage). As you noticed though, to run an offline install, you would need to either disable networking or at least disable any ipv4 / ipv6 address in the installer's network screen.
