Thanks for taking your time to report this issue and help making Ubuntu better.

I can confirm this issue on Ubuntu Hirsute. When attempting to install both packages the error message indicates that the underlying problem is that buildah conflicts with golang-github-containers-common, one of the dependencies of podman. (See below for details)

I notice that all three packages have newer versions in -proposed which haven't migrated yet, though I don't know if the new releases will resolve this.

$ sudo apt install podman buildah

podman is already the newest version (2.1.1+dfsg1-4ubuntu3).
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 golang-github-containers-common : Breaks: buildah (< 1.18.0+dfsg1-3~~) but 1.16.6+dfsg1-2ubuntu2 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Looks like the newer versions resolved this issue. Could you run `sudo apt update` and see if it works better now:

$ sudo apt install podman buildah

buildah is already the newest version (1.19.4+dfsg1-3ubuntu1).
podman is already the newest version (3.0.0+dfsg1-2ubuntu4).

(Note: it looks like installation replaced `fuse` with `fuse3`, though that seems unrelated)

Installation works now. Thanks!

Great. I'll set status to fixed.
