Issue Description

I'm getting an error when trying to install Xamarin on a Mac OS 14 machine via the following script:
 
brew install --cask xamarin-ios
brew install --cask xamarin-android

The error message is

Warning: xamarin-android has been deprecated because it is discontinued upstream! It will be disabled on 2025-08-20.
==> Downloading https://dl.xamarin.com/MonoforAndroid/Mac/xamarin.android-13.2.2.0.pkg

Error: Download failed on Cask 'xamarin-android' with message: Download failed: https://dl.xamarin.com/MonoforAndroid/Mac/xamarin.android-13.2.2.0.pkg

It looks like the Android file is no longer present at the legacy URL.

I am also experiencing this issue. Are there any known workarounds? Thanks in advance!

Looks like https://dl.xamarin.com/MonoforAndroid/Mac/xamarin.android-13.2.2.0.pkg is gone and maybe never coming back?

It was bound to happen sooner or later. The only way might be to host the pkg on your own and then use curl to pull it down and install it.

#!/bin/bash

# Exit immediately if a command exits with a non-zero status
set -e

# Define the download URL
XAMARIN_ANDROID_URL="https://aka.ms/xamarin-android-commercial-d17-8-macos"

# Define the file name
PKG_FILE="xamarin-android.pkg"

# Download the Xamarin.Android pkg
echo "Downloading Xamarin.Android from $XAMARIN_ANDROID_URL..."
curl -L -o "$PKG_FILE" "$XAMARIN_ANDROID_URL"

# Verify the file was downloaded
if [ ! -f "$PKG_FILE" ]; then
  echo "Download failed. Exiting."
  exit 1
fi

# Install the package
echo "Installing Xamarin.Android..."
sudo installer -pkg "$PKG_FILE" -target /

# Cleanup the downloaded package
rm -f "$PKG_FILE"

echo "Xamarin.Android installation completed successfully."

Add this as a new Task to the agent

The logs say " xamarin-android has been deprecated because it is discontinued upstream! It will be disabled on 2025-08-20." So it should be supported.

I can tell that this approach works. Thanks for this!

Worked for me. Thanks.

The posted workaround works. Leaving this open because the install Xamarin.Android task should be updated to point to the new file location.
