Comment 10 for bug 1926732

focal verification successful.

I changed the testing plan given that using the package from proposed with ubuntu-old-fashioned is not that easy.

I did now use launchpad itself to build (see https://code.launchpad.net/~toabctl/+livefs/ubuntu/focal/proposed):

- focal ubuntu-oci build: https://code.launchpad.net/~toabctl/+livefs/ubuntu/focal/proposed/+build/274969/+files/buildlog_ubuntu_focal_amd64_amd64-minimized-all_proposed_BUILDING.txt.gz
- focal ubuntu-base build: https://code.launchpad.net/~toabctl/+livefs/ubuntu/focal/proposed/+build/274966/+files/buildlog_ubuntu_focal_amd64_amd64-minimized-all_proposed_BUILDING.txt.gz
Testing the docker container tarball:

$ cat << EOF > Dockerfile
FROM scratch
ADD focal-minimal-cloudimg-amd64-root.tar.gz /
CMD ["/bin/bash"]
EOF

$ docker build .
