Linux arm64 is not supported yet by {}. Please try another b

Error message

Linux arm64 is not supported yet by {}. Please try another browser.

What it means

Returned by EdgeManager::request_latest_browser_version_from_online() on Linux ARM64 before any network call. Since Microsoft Edge has no Linux arm64 distribution, the function refuses to query the Edge updates endpoint. browser_name is interpolated, making the message reusable across Edge variants.

Solutions

Run on a platform where Microsoft Edge is distributed (x86_64 Linux, Windows, macOS, or mac-arm64).
Switch to a browser with arm64 Linux support (Firefox/geckodriver).
Provide a pre-installed Edge via --browser-path and a matching driver via --driver-path.
Confirm architecture detection is not falsely reporting arm64.

Defensive patterns

Strategy: validation

Validate before calling

# Bash: detect arm64 Linux before Edge browser discovery
if [ "$(uname -s)" = "Linux" ] && [ "$(uname -m)" = "aarch64" ]; then
  echo "Edge browser discovery unsupported on Linux arm64"; exit 1
fi

Try / catch

if let Err(e) = edge_manager.request_latest_browser_version_from_online("") {
    if e.to_string().contains("Linux arm64 is not supported yet by") {
        return configure_manual_edge_driver();
    }
    return Err(e);
}

Prevention

Provide Edge manually via --browser-path on arm64 Linux.
Use supported platforms for Edge automation.
Verify architecture detection in CI.

When it happens

Trigger: Selenium Manager on Linux ARM64 tries to discover the latest Edge browser version. The LINUX.is(os) && ARM64.is(arch) guard at line 401 fires immediately.

Common situations: ARM64 Linux CI workers; Graviton/Apple-Silicon-hosted Linux VMs; embedded arm64 devices where Edge is not shipped.
