> go get github.com/containers/image/v5@main > go mod tidy && go mod vendor This updates c/image with a new version of x/exp. That package has changed API in an incompatible way, so just bumping x/exp (as in https://github.com/containers/skopeo/pull/2060 ) would break Skopeo builds. This updates both c/image and x/exp in lockstep (and nothing needs updating in Skopeo itself for the x/exp breakage). Signed-off-by: Miloslav Trmač <mitr@redhat.com>
