Environment

Operator type:

/language go

Kubernetes cluster type:

kind

$ operator-sdk version

operator-sdk version: "v1.34.1", commit: "edaed1e5057db0349568e0b02df3743051b54e68", kubernetes version: "1.28.0", go version: "go1.21.7", GOOS: "linux", GOARCH: "amd64"

$ go version (if language is Go)

go version go1.22.2 linux/amd64

$ kubectl version

Client Version: v1.29.3
Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
Server Version: v1.29.2

Possible Solution

Additional context

This is the first time I've tried creating a operator. Just before this, I did an
operator-sdk init --domain license-operator.enfabrica.net --repo github.com/jrp-enf/license-operator
which was successful.

The problem was golang 1.22 doesn't work. Duplicate of #6681

Oops, no, this still fails with golang 1.21.7.

it fails like this:

The last problem was due to a bad go install - I had untarred 1.21 over 1.22 without removing the previous go install.
