How to Install Metasploit in Ubuntu: The Ultimate Guide for Ethical Hackers (2026)

Introduction: Why Choose Ubuntu for Metasploit?

If you are transitioning into the world of cybersecurity, learning how to install Metasploit in Ubuntu is a critical milestone. While specialized distributions like Kali Linux come with these tools pre-loaded, many professionals prefer the stability and versatility of a standard Ubuntu environment for their daily operations.

The Metasploit Framework is the world’s most used penetration testing software. It allows security teams to verify vulnerabilities, manage security assessments, and improve awareness. However, setting it up manually on a general-purpose OS like Ubuntu requires specific steps to ensure dependencies, databases, and network configurations are handled correctly.

In this extensive metasploit installation guide for Linux, we will cover every method available—from the quick Metasploit snap install to the professional Rapid7 installer script. By the end of this tutorial, you will have a robust ethical hacking Ubuntu setup ready for real-world scenarios.

Prerequisites: Preparing Your System

Before diving into the installation, it is vital to prepare your environment. Skipping these steps often leads to “dependency hell”—a situation where software libraries conflict with one another.

System Requirements

To run the framework smoothly, your system should meet these minimums:

• Operating System: Ubuntu 20.04 LTS, 22.04 LTS, or the newer Ubuntu 24.04.
• Processor: 2 GHz+ processor (Dual-core recommended).
• RAM: 4 GB RAM minimum (8 GB recommended for running multiple VMs).
• Disk Space: At least 10 GB of free space.

Updating the Repository Cache

First, open your terminal (Ctrl+Alt+T) and update your local package index. This ensures that when we request cybersecurity tools installation, we are pulling the latest stable versions.

sudo apt update && sudo apt upgrade -y

We also need to install curl and wget, which are command-line utilities for downloading files from the internet.

sudo apt install curl wget gnupg2 -y

Method 1: The Official Rapid7 Installer (Recommended)

For a professional environment, we strongly recommend using the official installer. This method installs the “Metasploit-Omnibus” package, which includes all necessary Ruby dependencies and libraries bundled together. This prevents conflicts with your system’s default Ruby version.

Step 1: Downloading the Installer Script

The Rapid7 installer script is the gold standard for setting up the framework. It automatically handles the GPG keys and repository additions for you. Run the following command:

curl https://raw.githubusercontent.com/rapid7/metasploit-omnibus/master/config/templates/metasploit-framework-wrappers/msfupdate.erb > msfinstall

Step 2: Executing the Script

Once downloaded, you need to make the script executable and run it. This process will add the official Rapid7 build server to your package manager’s source list.

chmod 755 msfinstall
./msfinstall

Note: Depending on your internet speed, this may take a few minutes. The script is pulling the entire framework core.

Step 3: Verifying the Installation

Once the script finishes, you can verify that the install metasploit framework ubuntu process was successful by checking the version.

msfconsole --version

You should see output similar to Framework: 6.x.x. This confirms the binary is correctly placed in your system path.

Method 2: Install Metasploit Framework on Ubuntu via Snap

If you prefer an isolated environment or want the absolute easiest method, the metasploit snap install is your best bet. Snaps are containerized software packages that are simple to create and install.

Run the Snap Command:Ubuntu comes with Snap pre-installed. Simply run:

sudo snap install metasploit-framework

Understanding Snap Limitations:While easy, Snaps run in a sandbox. This means they might have trouble accessing certain local files or network interfaces unless permissions are explicitly granted. This is why advanced users often prefer Method 1 for their setup metasploit ubuntu.

The Alias Trick:Snap commands can be long. To fix this, create an alias so you don’t have to type metasploit-framework.msfconsole every time:

sudo snap alias metasploit-framework

msfconsole 

Deep Dive: Database Configuration (PostgreSQL)

A common misconception is that installing the software is the final step. It isn’t. To effectively use penetration testing tools for Linux, you need a database.

Metasploit uses PostgreSQL to store results from scans (like Nmap), looted credentials, and host details. Without it, search commands are slow, and you cannot save your workspace state.

Step 1: Initialize the Database

If you installed via the Rapid7 script (Method 1), a helper script is provided to set up the database and create a user for you.

sudo msfdb init

This command performs the following actions:

1. Starts the PostgreSQL service.
2. Creates a database user named msf.
3. Creates a database named msf_database.
4. Writes the configuration to ~/.msf4/database.yml.

Step 2: Manual PostgreSQL Metasploit Setup (If Init Fails)

Sometimes the auto-init fails. Here is how to handle the postgresql metasploit setup manually:

Start the service:

Bash

sudo systemctl start postgresql
sudo systemctl enable postgresql

Switch to the postgres user and create the database:

sudo -u postgres createuser msf -P -S -R -D # (Enter a password when prompted)
sudo -u postgres createdb -O msf msf_database

Step 3: Checking Connectivity

Launch the console:

msfconsole

Inside the console, check the status:

db_status

Success: You should see [*] postgresql connected to msf_database.

Failure: If you see [*] postgresql selected, no connection, check your database.yml file to ensure the password matches what you created.

Exploring the Interface: Msfconsole on Ubuntu

Now that the msfconsole ubuntu interface is running, you have access to thousands of exploits.

• Auxiliary Modules: Used for scanning and sniffing (e.g., checking if a server is vulnerable).
• Exploits: Code that takes advantage of a vulnerability.
• Payloads: Code that runs after the exploit succeeds (e.g., a reverse shell).

Try searching for a module to test the database speed:

search type:exploit platform:linux

If the database is working, this search should be nearly instantaneous.

Troubleshooting Common Installation Errors

Even expert users run into issues. Here is how to fix metasploit database connection problems and other common hiccups.

Error 1: “Command not found”

If you installed via Method 1 but the command isn’t found, you likely need to add the binary path to your environment variables.

• Fix: Add /opt/metasploit-framework/bin to your $PATH.

Error 2: “Port 5432 already in use”

This happens if you have another instance of PostgreSQL running.

• Fix: Check what is running on the port using sudo netstat -plnt | grep 5432. You may need to stop a conflicting service or configure Metasploit to use a different port in the database.yml file.

Error 3: Ruby Version Mismatch

If you try to install from source (not covered here) or use an old repo, you might get Ruby errors.

• Fix: Always use the Rapid7 installer script as it bundles its own Ruby environment, completely bypassing version conflicts on your host OS.
