When using buildpack to build Go on an ARM64 host, the Tekton "prepare" and "results" steps fail with: Error executing command: fork/exec /tekton/scripts/script-0-....: exec format error The problem is the image used for both steps: https://github.com/knative/func/blob/a062cd28728aca02d162c9e1af3f32cf2ad1d5fa/pkg/pipelines/tekton/tasks.go#L87 https://github.com/knative/func/blob/a062cd28728aca02d162c9e1af3f32cf2ad1d5fa/pkg/pipelines/tekton/tasks.go#L193 After changing both images to the floating tag: image: docker.io/library/bash:5.1 buildpack work correctly.
