For anyone still stuck with this, this works. 😄 https://fabianlee.org/2022/08/02/buildah-installing-buildah-and-podman-on-ubuntu-20-04/

This works for me with Ubuntu 20.04 in Azure. I am using this to update the Azure DevOps agents because I am using buildah in the pipelines.
However, every now and then I get:

E: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process NNNN (apt-get)

On the install command, as it seems the update command leaves something in background and returns control before finishing... That is not very nice for unattended scripts.

Worked for me, thank you.

Also I'm pasting same instructions just in case something happens to the site hosting them

# prereq packages
sudo apt-get update

sudo apt-get install -y wget ca-certificates gnupg2

# add repo and signing key
VERSION_ID=$(lsb_release -r | cut -f2)

echo "deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/ /" | sudo tee /etc/apt/sources.list.d/devel-kubic-libcontainers-stable.list

curl -Ls https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_$VERSION_ID/Release.key | sudo apt-key add -

sudo apt-get update

# install buildah and podman
sudo apt install buildah podman -y

# fix known issue 11745 with [machine] entry
sudo sed -i 's/^\[machine\]$/#\[machine\]/' /usr/share/containers/containers.conf

@theJaxon thanks your answer works for me
