What steps did you take and what happened:

$ GO111MODULE=on go get -v -u github.com/vmware-tanzu/velero
go get: github.com/vmware-tanzu/velero@v1.5.1 requires
        github.com/kubernetes-csi/external-snapshotter/v2@v2.2.0-rc1 requires
        k8s.io/kubernetes@v1.18.0 requires
        k8s.io/api@v0.0.0: reading k8s.io/api/go.mod at revision v0.0.0: unknown revision v0.0.0

$ cd $(go env GOPATH)/src/github.com/vmware-tanzu/velero
$ go install .
go: github.com/kubernetes-csi/external-snapshotter/v2@v2.2.0-rc1 requires
        k8s.io/kubernetes@v1.18.0 requires
        k8s.io/kubectl@v0.0.0 requires
