cmd/go: download go1.22 for darwin/arm64: toolchain not available

[EwenQuim]

Go version

go1.22

Output of go env in your module/workspace:

go: downloading go1.22 (darwin/arm64)
go: download go1.22 for darwin/arm64: toolchain not available

What did you do?

rm -rf /usr/local/go/
rm -rf ~/go

Then used the installer.

Then ran the command go version.

go: downloading go1.22 (darwin/arm64)
go: download go1.22 for darwin/arm64: toolchain not available

go env also returns this result.

What did you see happen?

go: download go1.22 for darwin/arm64: toolchain not available, not much more

What did you expect to see?

go1.22

Thanks for reporting. What's the output of which go and GOTOOLCHAIN=local go env?

(As a side note, when it's working as intended, it's not necessary to rm -rf /usr/local/go before running the macOS installer to upgrade. If there is a previous Go installation there, the installer will let you know and take care of removing it.)

I've installed Go with homebrew and am on an Intel mac.

@adamdecaf Since your Go toolchain was installed using a different tool, it's hard to know if it's the same problem or a different homebrew-specific problem. Let's wait to hear back from @EwenQuim or someone who's able to reproduce this the problem that affects the Go installer from go.dev/dl/.

[fzipp]

GOMOD='/Users/adam/code/src/github.com/moov-io/irs/go.mod'

Does this go.mod file say go 1.22 or go 1.22.0? Because according to #62278 (comment) go 1.22 without a more specific toolchain directive is not sufficient.

I don't see anything wrong here, but it might be only my local setup

[seankhliao]

is this in a module (if yes, what's the go directive in there)?
what's the GOTOOLCHAIN env set to?
what's in /Users/ewenq/Library/Application Support/go/env?

[dmitshur]

@EwenQuim Thanks.

Can you post more complete steps for how to reproduce it, in an empty directory?

For example, does it reproduce if you do the following sequence?

cd $(mktemp -d)
go version

Is the GOTOOLCHAIN variable set in your environment?

I can only reproduce this if I set GOTOOLCHAIN to explicitly to "go1.22" (which is not a Go toolchain that exists):

$ cd $(mktemp -d)
$ GOTOOLCHAIN=go1.22 go version
go: downloading go1.22 (darwin/arm64)
^C

Otherwise it doesn't reproduce:

$ cd $(mktemp -d)
$ echo $GOTOOLCHAIN

$ go version
go version go1.22.0 darwin/arm64

@seankhliao

No

what's the GOTOOLCHAIN env set to?

Nothing

what's in /Users/ewenq/Library/Application Support/go/env?

[EwenQuim]

OK the problem is solved after I deleted the /Users/ewenq/Library/Application Support/go/env file, thank you very much !

Sorry for taking some of your time, I will explain the cause of the bug below if you're interested, but no need to search more.

[dmitshur]

Thanks. It's good to understand that the GOTOOLCHAIN=go1.22 line in the go/env file was causing this, and that it's not a problem with the Go installer.

A problem like that is fixable, as you've done, by unsetting the unwanted value with GOTOOLCHAIN=local go env -u GOTOOLCHAIN or by manually editing (or deleting) that file.
