Comprehensive Guide: Setting Up Invinsense Repository with Cryptographic Verification

This guide provides instructions for setting up the Invinsense repository with proper cryptographic verification across various environments, including bare-metal, containers, SystemV, and SystemD.

Prerequisites

• Root or sudo access (for bare-metal and some container environments)
• Internet connectivity
• Basic command-line knowledge

Universal Steps (All Environments)

1. Download the Invinsense GPG key:

   wget -O invinsense-repo-key.gpg https://invinsense.s3.us-east-2.amazonaws.com/4.x/apt/invinsense-repo-key.gpg

2. Verify the key's fingerprint (replace with the actual fingerprint):

   gpg --show-keys invinsense-repo-key.gpg

   Ensure the fingerprint matches: 8152 1539 216D 3D1F (example fingerprint)

3. Add the key to the trusted keyring:

   • For APT-based systems:

     sudo gpg --dearmor -o /usr/share/keyrings/invinsense-archive-keyring.gpg invinsense-repo-key.gpg

   • For RPM-based systems:

     sudo rpm --import invinsense-repo-key.gpg

4. Add the Invinsense repository:

   • For APT-based systems:

     echo "deb [signed-by=/usr/share/keyrings/invinsense-archive-keyring.gpg] https://invinsense.s3.us-east-2.amazonaws.com/4.x/apt stable main" | sudo tee /etc/apt/sources.list.d/invinsense.list

   • For RPM-based systems:

     sudo tee /etc/yum.repos.d/invinsense.repo << EOF
     [invinsense]
     name=Invinsense Repository
     baseurl=https://invinsense.s3.us-east-2.amazonaws.com/4.x/rpm
     enabled=1
     gpgcheck=1
     gpgkey=https://invinsense.s3.us-east-2.amazonaws.com/4.x/apt/invinsense-repo-key.gpg
     EOF

5. Update package lists:

   • For APT-based systems:

     sudo apt update

   • For RPM-based systems:

     sudo yum makecache

Environment-Specific Instructions

Bare-metal Systems

• Follow the Universal Steps above.
• Ensure you have sudo privileges.

Container Environments

• If running as root, omit sudo from the commands.
• If GPG is not available, install it:

  apt-get update && apt-get install -y gnupg

• For Docker containers, consider adding these steps to your Dockerfile.

SystemV Environments

• Follow the Universal Steps above.
• If using a SystemV init script, add the repository setup to your initialization scripts.

SystemD Environments

• Follow the Universal Steps above.
• Consider creating a oneshot systemd service to set up the repository on first boot:

  sudo tee /etc/systemd/system/invinsense-repo-setup.service << EOF
  [Unit]
  Description=Setup Invinsense Repository
  After=network.target
  
  [Service]
  Type=oneshot
  ExecStart=/path/to/your/setup/script.sh
  RemainAfterExit=true
  
  [Install]
  WantedBy=multi-user.target
  EOF

  Then enable and start the service:

  sudo systemctl enable invinsense-repo-setup.service
  sudo systemctl start invinsense-repo-setup.service

Verifying the Setup

1. Check the sources list (APT-based systems):

   cat /etc/apt/sources.list.d/invinsense.list

2. Check the repo file (RPM-based systems):

   cat /etc/yum.repos.d/invinsense.repo

3. List available Invinsense packages:

   • APT-based: apt search invinsense
   • RPM-based: yum list available | grep invinsense

Troubleshooting

1. If you encounter GPG errors:

   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 81521539216D3D1F

2. For RPM-based systems, if you see GPG check failures:

   sudo rpm --import https://invinsense.s3.us-east-2.amazonaws.com/4.x/apt/invinsense-repo-key.gpg

3. If the repository isn't accessible, check your network connection and firewall settings.

Security Considerations

• Always verify the GPG key fingerprint before adding it to your system.
• Regularly update your system to ensure you have the latest security patches.
• In production environments, consider setting up a local mirror of the repository for better control and security.

Removing the Repository

• APT-based systems:

  sudo rm /etc/apt/sources.list.d/invinsense.list
  sudo rm /usr/share/keyrings/invinsense-archive-keyring.gpg
  sudo apt update

• RPM-based systems:

  sudo rm /etc/yum.repos.d/invinsense.repo
  sudo rpm -e gpg-pubkey-216d3d1f-*
  sudo yum clean all

Final Notes

• Always refer to the official Invinsense documentation for the most up-to-date information.
• If you encounter persistent issues, contact Invinsense support for assistance.
