Ondřej Budai 29f66a251f go.mod: update github.com/containers/image/v5 
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:
--- FAIL: TestClientResolve (0.00s)
    client_test.go:31:
        	Error Trace:	client_test.go:31
        	Error:      	Received unexpected error:
        	            	Unknown key "keyPaths"
        	            	invalid policy in "/etc/containers/policy.json"

        	            	github.com/osbuild/osbuild-composer/internal/container.NewClient
        	            		/osbuild-composer/internal/container/client.go:123
        	            	github.com/osbuild/osbuild-composer/internal/container_test.TestClientResolve
        	            		/osbuild-composer/internal/container/client_test.go:29
        	            	testing.tRunner
        	            		/usr/lib/golang/src/testing/testing.go:1439
        	            	runtime.goexit
        	            		/usr/lib/golang/src/runtime/asm_amd64.s:1571
        	Test:       	TestClientResolve
    client_test.go:32:
        	Error Trace:	client_test.go:32
        	Error:      	Expected value not to be nil.
        	Test:       	TestClientResolve

 When run with an older containers-common, it succeeds:
 dnf install -y https://kojihub.stream.centos.org/kojifiles/packages/containers-common/1/40.el9/x86_64/containers-common-1-40.el9.x86_64.rpm
 go test -count 1 ./...
 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.

GPGME (golang)

Go wrapper for the GPGME library.

This library is intended for use with desktop applications. If you are looking to add OpenPGP support to a server application I suggest you first look at golang.org/x/crypto/openpgp.

Installation

go get -u github.com/proglottis/gpgme
