[yaxinlx]

What version of Go are you using (go version)?

Does this issue reproduce with the latest release?

Yes

What did you do?

$ git clone https://github.com/heketi/heketi.git
$ cd heketi
$ go mod init github.com/heketi/heketi
go: creating new go.mod: module github.com/heketi/heketi

What did you expect to see?

Use GOPROXY to fetch modules

What did you see instead?

But not, so many fetching fail.

This error happens when a custom remote import path has been used and the user can't query the domain. I was able to recreate this issue by bypassing the domain name resolution for k8s.io and golang.org via an edit to a local /etc/hosts file.

Yes, now ConvertLegacyConfig not use GOPROXY, I think we need fix this.
