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

$ go version
go version go1.15.7 darwin/amd64

Does this issue reproduce with the latest release?

Yes.

It can be reproduced in Go 1.15.7 and also Go 1.15.6, although it did not reproduce with Go 1.15.6 when it was released, which suggests something external changed (maybe a new v0.1.0 tag or rewritten history in x/tools).

(Go 1.14 doesn't have this test.)

What operating system and processor architecture are you using (go env)?

What did you do?

$ go test -v -count=1 -run='TestScript/get_update_unknown_protocol' cmd/go

What did you expect to see?

A passing test, like on tip.

Approved as a test fix. Only Go 1.15 needs the fix.

[release-branch.go1.15] cmd/go: fix get_update_unknown_protocol test
9bb97ea 
This test needs to run in GOPATH mode. It broke when a go.mod file was
added to github.com/golang/example. This change sets GO111MODULE=off,
which matches master since CL 255051.

Fixes #43861
