Ubuntu ARM images failing to build on "no image found in image index for architecture amd64, variant "", OS linux"

Recently all Ubuntu ARM images started to fail at the step that is trying to pull the base image. Example of failing job: https://salsa.debian.org/salsa-ci-team/pipeline/-/jobs/6477097

This can easily be reproduced locally, but I did not immediately figure out what is wrong as the exact same command works for Debian equivalent just fine:

± podman run --interactive --network host --tty --rm --shm-size=1G --volume=$PWD:/tmp/test --workdir=/tmp/test docker.io/arm64v8/debian:trixie bash
Trying to pull docker.io/arm64v8/debian:trixie...
Getting image source signatures
Copying blob 6f4ac25c892a [===============================>------] 43.6MiB / 51.1MiB

± podman run --interactive --network host --tty --rm --shm-size=1G --volume=$PWD:/tmp/test --workdir=/tmp/test docker.io/arm64v8/ubuntu:oracular bash
Trying to pull docker.io/arm64v8/ubuntu:oracular...
Error: choosing an image from manifest list docker://arm64v8/ubuntu:oracular: no image found in image index for architecture amd64, variant "", OS linux
