ko doesn't work with toolchain directive in go.mod about ko HOT 6 CLOSED

Could this just be that ko needs to be rebuilt with a modern version of the go stdlib?

from ko.

This seems like a likely explanation. The error seems to be coming from here, where we call packages.Load which comes from the stdlib the binary was built with:

The good news is that we're building with 1.21 now, since #1137, which just needs to be released.

That PR was included in the 0.15.1 release which the action is installing but the error is still there. hmm 😕

Weird, I'm not able to reproduce with the latest ko

Is it possible your Go version is pre-1.21?

$ go version
go version go1.21.4 darwin/arm64

Thanks!
It seems the problem was indeed that go 1.19 was used for the tests.
(e2e test was using 1.19)
Fixed by knative-extensions/security-guard#265

Thanks for following up!
