Install Issue - Ubuntu Image on Mac M1 Pro about syft

[spiffcs]

Nice catch @Lachlan-White

It looks like our current .goreleaser.yaml doesn't account for a v7 distribution here.

This section does not exist in our release file:

    # GOARM to build for when GOARCH is arm.
    # For more info refer to: https://go.dev/doc/install/source#environment
    #
    # Default: [ 6 ]
    goarm:
      - 6
      - 7

Reading again, it also looks like we only support arm64 as a release candidate: ARM64 (64-bit): Also known as ARMv8

  - id: linux-build
    dir: ./cmd/syft
    binary: syft
    goos:
      - linux
    goarch:
      - amd64
      - arm64
      - ppc64le
      - s390x

To reproduce this I also ran

❯ docker run -it mcr.microsoft.com/powershell:latest /bin/sh
# uname -m
x86_64

It looks like for the powershell latest docker image the arch should be x86_64) arch="amd64" ;;

I was also able to install syft successfully when running that image interactively:

# curl -sSfL https://raw.githubusercontent.com/anchore/syft/main/install.sh | sh -s -- -b /usr/local/bin
[info] fetching release script for tag='v1.4.1'
[info] using release tag='v1.4.1' version='1.4.1' os='linux' arch='amd64'
[info] installed /usr/local/bin/syft

Do you have any more information on why your mcr.microsoft.com/powershell:latest /bin/sh is returning an arm32 architecture?

I can talk with the team about updating our release assets, but want to also get to the bottom of why we're seeing different outcomes on our respective machine.

Here is the link to the powershell official docker image along with the tags and their supported architecture:

Hey @spiffcs, thanks for the quick response!

Have no idea why the default output of the Microsoft image is returning an arm32 by default.

I might just force the version specifically in arm64 which would fix my issue, but it is an interesting scenario.

If you had anything you wanted me to test on my local to help, just let me know

If you run this on your local what's your result?

docker run  -it mcr.microsoft.com/powershell:latest /bin/sh
# uname -a
Linux 83b1dbc1234f 6.6.26-linuxkit #1 SMP PREEMPT_DYNAMIC Sat Apr 27 04:15:35 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

I copied your Dockerfile and removed the powershell lines and was able to get a successful install.

What happens if you do the same for the alpine version or any explicitly tagged x86_64 arch?

docker run -it mcr.microsoft.com/powershell:lts-alpine-3.17 /bin/sh
