Looks like the go.mod toolchain update brings in an official version of Go that matches up with what we use for our build, and the match caused the exact cache collision I was hitting that we applied a fix for in #1994 for 1.26.

The root cause though is that we're using the ambient Go. We should install the mingw installation tool using the Go toolset installed by eng/run.ps1 etc.

go/eng/pipeline/stages/run-stage.yml

Line 231 in 9e0d9fd

go install github.com/microsoft/go-infra/cmd/getmingw

[dagood]

I'll make a fix for that.

@dependabot rebase

[dependabot]

Looks like this PR has been edited by someone other than Dependabot. That means Dependabot can't rebase it - sorry!

If you're happy for Dependabot to recreate it from scratch, overwriting any edits, you can request @dependabot recreate.

[dagood]

@dependabot recreate

[gdams]

We'll need to bump the golanglint docker image version again

[dependabot]

Looks like golang.org/x/net is up-to-date now, so this is no longer needed.
