Support aarch64 architecture for Linux OS #276

Description

@opoku

Description

It appears that the linux version only supports the x86-64 architecture. Since Linux also runs on other architectures (in my specific case 64-bit arm), it would be useful to either generate a build for that architecture or at the minimum check in the installation script for non-x86-64 architectures and show an appropriate error message instead.

It currently indicates a successful installation even though the resulting binary does not actually run successfully.

Requirements

  • I've read and understood the Contributing guidelines and have done my best effort to follow them.
  • I've read and agree to the Code of Conduct.
  • I've searched for any related issues and avoided creating a duplicate issue.

    Hi @opoku 👋🏻

    Thanks a lot for taking the time to share your issue! 🙇🏻 This is great feedback and it sounds like we should consider supporting Linux on non-x86-64 architectures.

    I agree with your suggested next steps:

    1. Update Install Scripts to error on Linux when the architecture is not x86-64. The error message can display steps to manually compile the project.
    2. Update our CI/CD to build and publish aarch664 on Linux.

    ❓ Question for you - what hardware are you running your Linux distro on? Macbook aarm, Raspberry Pi, or something else? I'm asking to help us setup a virtual machine that can we can test on.

    @mwbrooks I'm on a M1 MacBook Pro running Linux (via the Asahi Linux project). But I think a recent raspberry pi is a good approximation too.

    I'm having the same issue (got "📺 Success! The Slack CLI is now installed!" but the binary's not compatible) -- I'm on a Raspberry Pi 3b.

    @opoku @libbybeer Hello! 👋 We're planning to land support in our upcoming release, but development builds might find this sooner with the following command:

    curl -fsSL https://downloads.slack-edge.com/slack-cli/install-dev.sh | bash

    🔗 https://github.com/slackapi/slack-cli/releases/tag/dev-build

    I'm hoping this installs as expected but will follow up with fixes however needed 🫡
