Requirements

• 64-bit host, hardware virtualization support (Intel VT-x / AMD-V)
• Minimum 4 vCPU / 8 GB RAM / 40 GB disk for light use; scale up for larger labs
• Ubuntu 26.04 LTS ("27H1 Resolute") for the network install method

Installation

Option 1 — Network install (recommended)

Run the network install script on a fresh Ubuntu 26.04 server:

curl -fsSL https://codeberg.org/api/packages/netkillui/generic/pnetlab-core-assets/0.channel/pnetlab-network-install-latest.sh | sudo bash -s -- --yes --release latest

The script partitions storage, installs dependencies, and pulls the latest PNetLab v8 package automatically.

Option 2 — OVA (autoinstaller)

1. Download the OVA from the table above.
2. Import it into VMware Workstation/ESXi or VirtualBox.
3. Power on the VM. It boots into an unattended autoinstaller that partitions the disk and installs Ubuntu 26.04 + PNetLab v8 with no manual input beyond DHCP/static IP choice.
4. Once the install finishes and the VM reboots, log in to the web UI at https://<host-ip>/.

Updating

PNetLab v8 ships update packages through its built-in update mechanism.

sudo pnetlab-update

This checks the configured release channel, downloads the newest package, and applies it in place. Review the changelog before updating a production lab host.

Manual upgrade (if pnetlab-update is unavailable)

1. Back up /opt/unetlab (or your configured lab data path) and any custom node images.
2. Download the target release package (placeholder link above).
3. Install it:

sudo dpkg -i pnetlab_<version>_amd64.deb
sudo apt-get -f install

4. Reboot and verify the web UI and running labs come back up correctly.
