What Renovate type, platform and version are you using?

Self hosted using Gitlab CI scheduled pipeline.

With latest renovate/renovate docker image

$ renovate --version
23.5.0

Describe the bug

Renovate runs with GOPROXY set to GOPROXY=<internal-proxy>|https://proxy.golang.org

Client repo configure a custom postUpgradeTasks (that renovate allowed):
go mod tidy

Client repo has the following in go.mod

        k8s.io/api v0.0.0-20191004102349-159aefb8556b
        k8s.io/apimachinery v0.0.0-20191004074956-c5d2f014d689
        k8s.io/client-go v11.0.1-0.20191029005444-8e4128053008+incompatible
        k8s.io/klog v1.0.0

To Reproduce

Its happening to an internal repo so its hard to publish the repo for repoducable.

Additional context

I tried to cd /tmp/renovate/repos/..../my-repo and run go mod tidy and it was fine.

GOSUMDB=off

> go version
go version go1.15 linux/amd64

[sluongng]

Looking at this closely, I can see that the module is being resolved here is k8s.io/klog/v2/v2@v2.3.0 instead of k8s.io/klog/v2@v2.3.0 ?

[rarkins]

Without a reproduction, it's hard to troubleshoot anything. Is klog the dependency that's being updated in this branch/MR?

Closing this in the absence of any reproduction or progress. Small chance it's related to #7233
