This broke the build for containerd, and also for docker.io which embeds containerd:
https://buildd.debian.org/status/fetch.php?pkg=docker.io&arch=s390x&ver=20.10.0%7Erc1%2Bdfsg1-1&stamp=1606547204&raw=0 /<<PKGBUILDDIR>>/.gopath/src/ github.com/containerd/containerd/vendor/sigs.k8s.io/structured-merge-diff/v3/value (vendor tree) /usr/lib/go-1.15/src/sigs.k8s.io/structured-merge-diff/v3/value (from $GOROOT) /<<PKGBUILDDIR>>/.gopath/src/sigs.k8s.io/structured-merge-diff/v3/value (from $GOPATH) (the latest containerd builds were still against k8s-structured-merge-diff v3, so they succeeded, only this docker.io build was late enough to pick up the v4) By any chance, do you know if simply patching to use v4 instead of v3 in the import path will work? Or is there another way to handle this? Cheers, Arnaud
