How to go get github.com/fxamacker/cbor/v2 with Go 1.10?

Question

I tried running go get -u github.com/fxamacker/cbor/v2, but I get this error:

package github.com/fxamacker/cbor/v2: cannot find package "github.com/fxamacker/cbor/v2" in any of:
    /usr/local/go/src/github.com/fxamacker/cbor/v2 (from $GOROOT)
    /go/src/github.com/fxamacker/cbor/v2 (from $GOPATH)

I get the same error when I run without the -u flag.

I am using Go 1.10 because one of the requirements for my project is that it supports Windows Vista, and Go 1.10 is the latest version of Go that will build for Vista (source).

Here is a Dockerfile to reproduce this:

FROM golang:1.10.8-alpine@sha256:549535d72baf28b3d1470ef9fcc6d4e0cb52c7fc3012655a659b65eaf942ec63 as builder

RUN apk add --no-cache git

ENV GOOS=windows

ARG GOARCH

RUN go get -u github.com/fxamacker/cbor/v2

You can reproduce with the issue with the following command:

docker build -t test --build-arg GOARCH=386 .

This project is still available: https://pkg.go.dev/github.com/fxamacker/cbor/v2

Why does my go get fail?

I looked at the go.mod for the package. It requires a minimum go of 1.12 on master. Could this be why the go get fails?
