+CLI `2.0.3` does not contain a `linux-arm64` archive. On an ARM64 Linux host,

+
+```bash
+sudo apt-get update

+Run the clone command from a directory where the temporary `amber_cli/`
+checkout can be created. The next CLI release workflow now builds and smoke
+tests a native `linux-arm64` archive on a GitHub-hosted ARM64 Linux runner.
