How to Install Kali Linux on Android with Termux (2025 Guide)

Kali Linux is a powerhouse for cybersecurity enthusiasts, offering tools for penetration testing, ethical hacking, and network analysis. While it’s traditionally used on PCs, you can now run it on your Android device using Termux—no need for a laptop or complex setups. In this guide, I’ll walk you through the process step-by-step, ensuring you get Kali up and running smoothly.

What You’ll Need

1. An Android Device (Android 8.0 or higher): Older versions might work but aren’t recommended.
2. At least 4GB of Free Storage: Kali Linux and its tools require space.
3. A Stable Internet Connection: For downloading packages.
4. Termux (Installed via F-Droid): The Play Store version is outdated, so grab it from F-Droid.
5. Patience: The installation takes 15–30 minutes, depending on your internet speed.

Step 1: Install and Configure Termux

1. Download Termux from F-Droid:
   Open F-Droid, search for “Termux,” and install it. Avoid third-party sources to prevent security risks.
2. Update Packages:
   Launch Termux and refresh its package lists:

   pkg update && pkg upgrade -y  

Tap “Allow” if prompted for storage permissions.

3. Install Proot-Distro:
   This tool lets you run Linux distributions on Android:

   pkg install proot-distro -y  

Step 2: Install Kali Linux

1. Fetch Kali’s RootFS:
   Use proot-distro to install Kali:

   proot-distro install kali  

Confirm with Y when prompted.

2. Launch Kali Linux:
   Start the environment with:

   proot-distro login kali  

You’ll see a root@localhost prompt—you’re now inside Kali!

Step 3: Set Up Kali Tools

By default, Kali in Termux is minimal. Let’s add essential tools:

1. Update Kali’s Repositories:

   apt update && apt upgrade -y  

2. Install Core Packages:
   Grab the basics like nmap, wireless-tools, and the Kali menu:

   apt install kali-menu nmap git python3 -y  

3. Optional: Install a GUI (Graphical Interface):
   If you want a desktop experience:

• Install TigerVNC and XFCE4:
  apt install tigervnc-standalone-server xfce4 kali-defaults -y
• Start the VNC server:
  vncserver -localhost no
  Use a VNC viewer app (like bVNC) to connect to localhost:1.

Troubleshooting Common Issues

• “Command Not Found” Errors: Ensure you’re inside the Kali environment with proot-distro login kali.
• Storage Permission Denied: Grant Termux storage access in Android settings.
• VNC Connection Fails: Double-check your VNC server is running and the port is correct.

Ethical Reminder

Kali Linux is packed with powerful tools. Always use it ethically and only on networks/devices you own or have explicit permission to test. Unauthorized hacking is illegal!

FAQs

1. Does this require rooting?
   No! Termux uses a proot environment, so rooting isn’t necessary.
2. Will this harm my phone?
   Kali runs in an isolated environment, so your Android OS remains safe.
3. Can I uninstall Kali later?
   Yes! Just delete the Termux app or run:

   proot-distro remove kali  

Final Thoughts

Running Kali Linux on Android via Termux is a game-changer for on-the-go security testing. While performance depends on your device, it’s a handy way to practice ethical hacking or troubleshoot networks. Remember, with great power comes great responsibility—use Kali wisely!
