Installation Flow

The installation process is designed to be straightforward with minimal user input required:
1

Download the ISO

Download the UTMStack v11 Community Edition ISO:Download utmstack-v11-autoinstall.isoSave the ISO file to a location accessible to your virtualization platform.
2

Attach ISO and Boot

Attach the UTMStack ISO to your virtual machine and boot from it. The automated installer will launch automatically.
3

Create User Credentials

During installation, you will be prompted to:
  • Create a username (no default credentials exist)
  • Set a strong password
Store these credentials securely - they are required for all future system access.
4

Configure Network Settings

Choose your network configuration:
  • DHCP (automatic IP assignment)
  • Static IP (manual configuration)
Ensure your network settings allow outbound connectivity for package downloads.
5

Automatic Package Installation

The system automatically installs essential packages:
  • openssh-server - Remote SSH access
  • curl, wget - Network utilities
  • git - Version control
  • vim - Text editor
  • htop - Process monitor
  • net-tools - Network utilities
6

First Boot Configuration

On first boot, the following occurs automatically:
  • UTMStack installer launches
  • Custom MOTD with UTMStack branding displays
  • Installation logs begin writing to /var/log/utmstack/
The entire installation process typically takes 15-30 minutes depending on hardware and network speed.

​
Post-Installation Steps

​
1. Log In

Once installation completes, log in using the credentials you created during the setup process. 
# Login via console or SSH
ssh username@your-server-ip
SSH is enabled by default and ready for remote access immediately after installation.

​
2. Monitor Installer Progress

The UTMStack installer runs automatically on first boot. Monitor its progress: 
tail -f /var/log/utmstack/installer.log
Keep the log monitoring terminal open during installation to catch any potential issues in real-time.

​
3. Optional Setup Wizard

After the main installation completes, you can run the setup wizard to configure additional settings: 
utmstack-setup
The setup wizard currently handles:
  • Timezone configuration - Set your local timezone
Note: The hostname is already configured during the initial installation process and does not need to be set again.

​
4. System Verification

After installation, verify your system is configured correctly: 
lsb_release -a
# Expected: Ubuntu 24.04.3 LTS
All UTMStack scripts are centrally located for easy management and access.

​
Script Location

Primary Directory: /opt/utmstack/
Purpose: Main UTMStack installer launcherExecution: Runs automatically on first bootManual Run:
sudo /opt/utmstack/start.sh
Purpose: Post-installation setup wizard (timezone configuration)Execution: Optional, run manually after installationSymlink: utmstack-setup
For quick access, symlinks are created under /usr/local/bin/: 
utmstack-install  → /opt/utmstack/start.sh
utmstack-setup    → /opt/utmstack/finish-install-setup.sh
You can run these commands from any directory without specifying the full path.

​
Log Files

All installation and system logs are centralized for easy troubleshooting.

​

sudo cat /var/log/utmstack/installer.log

​
Troubleshooting

Solution:
  1. Check the installer log for errors: 
    tail -f /var/log/utmstack/installer.log
  2. Verify network connectivity: 
    ping -c 3 8.8.8.8
  3. Check if the installer process is running: 
    ps aux | grep utmstack
Solution:
  1. Verify SSH service is running: 
    sudo systemctl status ssh
  2. Check firewall rules: 
    sudo ufw status
  3. Verify network configuration: 
    ip addr show
Solution:
  1. Review the complete log: 
    cat /var/log/utmstack/installer.log
  2. Check for specific error messages
  3. Verify system resources meet requirements
  4. Contact support with log file if issue persists
Solution:
sudo /opt/utmstack/start.sh
Re-running the installer may reset existing configurations. Backup any custom settings first.

​
Security Considerations

Basic Security Hardening Included

The ISO includes basic security hardening measures:
  • No default credentials (user creates during installation)
  • SSH configured with secure defaults
  • Minimal exposed services
  • System updates applied during installation

​
Post-Installation Security Recommendations

1

Configure Firewall

Set up UFW firewall rules to restrict access. See Firewall Rules for detailed configuration.
2

Enable SSL/TLS

Configure SSL certificates for secure web access. See SSL Certificate for instructions.
3

Update System

Keep your system updated with the latest security patches:
sudo apt update && sudo apt upgrade -y
4

Harden SSH

  • Disable password authentication (use keys only)
  • Change default SSH port
  • Restrict SSH access by IP
