I’m trying to fly launch a new Golang application. However, building failed with the following error:

Dockerfile is the following (generated automatically):

ARG GO_VERSION=1
FROM golang:${GO_VERSION}-bookworm as builder

WORKDIR /usr/src/app
COPY go.mod go.sum ./
RUN go mod download && go mod verify
COPY . .
RUN go build -v -o /run-app .


FROM debian:bookworm

COPY --from=builder /run-app /usr/local/bin/
CMD ["run-app"]

My flyctl version is v0.2.59.

Replace the word “bookworm” with “bullseye” (twice) or upgrade to a newer version of go.

bookworm is a newer version of debian, 1.18 is an older version of go.
