NA as this LUCI builder infra related Issue
What did you do?
When I try to run trybot go1.26-linux-s390x and go1.27-linux-s390x LUCI builders fail during bootstrap, while go1.25-linux-s390x and gotip-linux-s390x complete successfully on the same builder machines.
What did you see happen?
Failing with below error:
Building Go cmd/dist using /home/swarming/.swarming/w/ir/cache/tools/go_bootstrap. (go1.24.6 linux/s390x)
Building Go toolchain1 using /home/swarming/.swarming/w/ir/cache/tools/go_bootstrap.
go: go.mod requires go >= 1.26 (running go 1.24.6; GOTOOLCHAIN=local)
go tool dist: FAILED: /home/swarming/.swarming/w/ir/cache/tools/go_bootstrap/bin/go install -tags=math_big_pure_go compiler_bootstrap purego bootstrap/cmd/...: exit status 1
It's unclear why this failure occurs only for the go1.26 and go1.27 trybots, as LUCI provides the supported minimum bootstrap(/home/swarming/.swarming/w/ir/cache/tools/go_bootstrap) Go version (go1.24.6) for both.
What did you expect to see?
No Bootstrap failure
