Describe the bug
Ubuntu 20.04 (Subiquity) under Linux network installs needs to be updated from 20.04.2 to 20.04.3, as the old ISO file has been removed from http://releases.ubuntu.com/focal/, which results in a 404 error during boot.

You may have outdated code, latest release resolves this. Make sure you are at least on 2.0.47 or using the hosted version.

The ISO file was downloaded from https://boot.netboot.xyz/ipxe/netboot.xyz.iso about an hour ago at this point.

Are you using the docker container on your network? Latest versions on boot.netboot.xyz are all 20.04.3.

~ % curl -s https://boot.netboot.xyz/ubuntu.ipxe | grep version_number
set version_number 20.04.3
set version_number 21.04
isset ${dhcp-server} && set netboot_params ip=dhcp url=http://releases.ubuntu.com/${codename}/ubuntu-${version_number}-live-server-${os_arch}.iso || set netboot_params

I ran into the same issue. I wasn't using dhcp, so it was attempting to use the interactive_netmount functionality. However, that functionality appears to have a bug on the LTS point releases. I have filed an appropriate issue upstream here: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1948884
