oscap-docker traceback when scanning ubuntu 22.04 image

[jan-cerny]

Description of Problem:

When scanning an Ubuntu 22.04 image using oscap-docker, a traceback happens

This problem has been discovered during a review of #1931 but isn't caused by that PR.

OpenSCAP Version:

openscap-1.3.7-1.fc37.x86_64
podman-4.3.1-1.fc37.x86_64

Operating System & Version:

F 37

Steps to Reproduce:

1. sudo systemctl start podman
2. sudo podman pull ubuntu:22.04
3. sudo oscap-podman ubuntu:22.04 xccdf eval --profile xccdf_org.ssgproject.content_profile_standard /usr/share/xml/scap/ssg/content/ssg-ubuntu2204-ds.xml

Actual Results:

[jcerny@thinkpad ~]$ sudo oscap-docker image ubuntu:22.04 xccdf eval --profile xccdf_org.ssgproject.content_profile_standard /usr/share/xml/scap/ssg/content/ssg-ubuntu2204-ds.xml

Expected Results:

no traceback, a scan of the given image is successfully completed

Additional Information / Debugging Steps:

[jcerny@thinkpad ~]$ sudo podman images ubuntu:22.04
REPOSITORY                TAG         IMAGE ID      CREATED      SIZE
docker.io/library/ubuntu  22.04       58db3edaf2be  4 weeks ago  80.3 MB
docker.io/library/ubuntu  latest      58db3edaf2be  4 weeks ago  80.3 MB

• When doing the same thing with an Ubuntu 20.04, the traceback doesn't happen and a scan is succesfully completed. Therefore, the problem might be related to the specific image.
• When using oscap-podman, the traceback doesn't happen and a scan is succesfully completed.

This problem is also reproducible on Ubuntu 22.04 server virtual machine with docker.io 20.10.12-0ubuntu4 with OpenSCAP from current upstream maint-1.3 branch as of 2023-02-28 as of HEAD 7111011, see below:

I can't reproduce this issue.

I'm using fedora 37.

$ rpm -q openscap
openscap-1.3.7-1.fc37.x86_64
$ rpm -q podman
podman-4.4.2-2.fc37.x86_64

I notice that I'm using a later version of podman, perhaps that's important?
