What did you do?

go clean --modcache
go build

What did you expect to see?

Clean build with no errors

What did you see instead?

cannot load golang.org/x/sys/unix: unexpected status (https://proxy.golang.org/golang.org/x/sys/@v/v0.0.0-20190624145334-c5567b49c5d0.zip): 400 Bad Request

The build works if I unset the GOPROXY.

Where did that pseudoversion come from? The correct pseudoversion for that commit seems to be v0.0.0-20190624142023-c5567b49c5d0, with a slightly different timestamp. #32662 (comment) is the reason it's failing.

The issue got fixed after I updated the package. I don't touch the mod file directly, must be one the steps in the build that updated the version. I run goimports and go test as part of my build.

I'm glad it's working for you, but I'd really like to know where the bad version came from, especially since it'll break in 1.13. Can you tell me anything about what might have caused it?

[gobins]

I spent some time trying to reproduce the issue but have not been successful.
The go version I started out was 1.12.

[heschi]

Very strange. Well, thanks for trying.
