The official Fedora guide (c. 2018) to installing the ever-popular ruby-based Metasploit automated scan-and-exploit framework is slightly outdated and indecisive. Please find below an updated quick installation recipe for your pleasure and leisure:

# RedHat Metasploit-Framework Installer # https://foxpa.ws/install-metasploit-framework-on-redhat # --- # Obtain the latest release from GitHub # You can git clone git://github.com/rapid7/metasploit-framework.git # however I've had problems syncing on Qubes and the master .zip will always work. # Consider using git for future updates. You may wish to add such to your crontab. # Alternatively, use the Metasploit-hosted tarball at # http://downloads.metasploit.com/data/releases/framework-latest.tar.bz2 sudo bash cd /opt wget https://github.com/rapid7/metasploit-framework/archive/refs/heads/master.zip unzip master.zip mv metasploit-framework-master metasploit # Install Ruby dependencies dnf -y install ruby-irb rubygems rubygem-bigdecimal rubygem-rake rubygem-i18n rubygem-bundler dnf builddep -y ruby dnf -y install ruby-devel libpcap-devel gem install rake # Install PostgreSQL (SQLite is no longer supported) dnf -y install postgresql-server postgresql-devel gem install pg # Symlink the Metasploit tools to a PATH'd location: ln -sf /opt/metasploit/msf* /usr/local/bin/ # Enable raw socket modules: gem install pcaprub # Install additional dependent Gems bundle install --gemfile /opt/metasploit/Gemfile

You can download this script from https://foxpa.ws/files/install-metasploit.sh, simply chmod +x it executable and ./ it. In a few minutes you should be returned to a prompt with no user intervention necessary and a working installation of Metasploit.

Now continue to setup the PostgreSQL database for Metasploit by following Fedora Project Wiki > Metasploit Postgres Setup (https://fedoraproject.org/wiki/Metasploit_Postgres_Setup).
