[kindermoumoute]

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

$ go version
go version go1.12 darwin/amd64

Does this issue reproduce with the latest release?

Yes

What did you do?

Use go index:

export GOPROXY=https://proxy.golang.org
go mod download

What did you expect to see?

Should download modules.

What did you see instead?

go: github.com/tsenart/[email protected]+incompatible: unexpected status (https://proxy.golang.org/github.com/tsenart/vegeta/@v/v12.1.1-0.20190104112155-65db074680f5+incompatible.info): 410 Gone

Where did that pseudoversion come from? 65db074680f5 in that repository is tagged as v12.2.0, so it's questionable to use a pseudoversion to refer to it. I'm not sure offhand why the mirror is rejecting the request though.

In case this can help:

$ cat go.mod | grep vegeta
	github.com/tsenart/vegeta v12.1.1-0.20190104112155-65db074680f5+incompatible
$ cat go.sum | grep vegeta

That pseudo-version would be an appropriate name for the commit if the tag was not added until some later point. (This is one of the cases described in #27173 (comment), in which we need to accept a pseudo-version below what is implied by the current tags.)

For (my) reference, a good thing to try in the future for issues similar to this one is to run the same command with export GOPROXY=direct and see if the error happens as well. In that case, the problem is in cmd/go rather than the mirror.

In this case, it seems the problem only happens with GOPROXY set to mirror and not direct:

$ export GOPATH=$(mktemp -d)
$ export GOPROXY=https://proxy.golang.org
$ go mod download -json github.com/tsenart/[email protected]+incompatible
go: finding github.com/tsenart/vegeta v12.1.1-0.20190104112155-65db074680f5+incompatible

We've released a change that improves this behavior; the query that previously returned an error will now return v12.2.0+incompatible, since that's the more canonical way to reference that commit. If that causes you any trouble please let us know.
