Version 5.22 introduced a new option to /etc/containers/policy.json called
keyPaths, see
https://github.com/containers/image/pull/1609
EL9 immediately took advantage of this new feature and started using it, see
04645c4a84
This quickly became an issue in our code: The go library (containers/image)
parses the configuration file very strictly and refuses to create a client
when policy.json with an unknown key is present on the filesystem. As we
used 5.21.1 that doesn't know the new key, our unit tests started to
failing when containers-common was present.
Reproducer:
podman run --pull=always --rm -it centos:stream9
dnf install -y dnf-plugins-core
dnf config-manager --set-enabled crb
dnf install -y gpgme-devel libassuan-devel krb5-devel golang git-core
git clone https://github.com/osbuild/osbuild-composer
cd osbuild-composer
# install the new containers-common and run the test
dnf install -y https://kojihub.stream.centos.org/kojifiles/packages/containers-common/1/44.el9/x86_64/containers-common-1-44.el9.x86_64.rpm
go test -count 1 ./...
# this returns:

When run with an older containers-common, it succeeds:

PASS
To sum it up, I had to upgrade github.com/containers/image/v5 to v5.22.0.
Unfortunately, this wasn't so simple, see
go get github.com/containers/image/v5@latest
go: github.com/containers/image/v5@v5.22.0 requires
github.com/letsencrypt/boulder@v0.0.0-20220331220046-b23ab962616e requires
github.com/honeycombio/beeline-go@v1.1.1 requires
github.com/gobuffalo/pop/v5@v5.3.1 requires
github.com/mattn/go-sqlite3@v2.0.3+incompatible: reading github.com/mattn/go-sqlite3/go.mod at revision v2.0.3: unknown revision v2.0.3
It turns out that github.com/mattn/go-sqlite3@v2.0.3+incompatible has been
recently retracted https://github.com/mattn/go-sqlite3/pull/998 and this
broke a ton of packages depending on it. I was able to fix it by adding
exclude github.com/mattn/go-sqlite3 v2.0.3+incompatible
to our go.mod, see
https://github.com/mattn/go-sqlite3/issues/975#issuecomment-955661657
After adding it,
go get github.com/containers/image/v5@latest
succeeded and tools/prepare-source.sh took care of the rest.
