ℹ️ Additional Information

🔌 If all interfaces fail:

• Double-check the physical connections:

• Is the NIC port connected?

• Are there link lights on both the NIC and the switch?

• Is the Ethernet cable securely connected and undamaged?

• Is the network drop connected to your telecommunications room?

• Is a patch cable properly connected between your patch panel and switch?

• Inspect your switch:

• Is DHCP enabled on the port?

• Are any port security policies preventing the server from connecting?

🧑‍💻 Advanced: Verify Network Interface Configurations

If your /etc/network/interfaces file has been manually edited, the ggrock-linux-configurator may fail during installation.

To verify and correct this:

1. Run ip a in the terminal and note each interface name.
2. Run cat /etc/network/interfaces and ensure each active NIC has a corresponding entry.
3. For each NIC not in the DOWN state, add an entry like:

   iface eno3 inet dhcp

4. After updating the file, re-run the ggRock installation.

🛠️ Temporary Workaround

To bypass the issue and continue with the installation:

• Choose "No" when prompted to enable the VM bridge.
• Contact ggCircuit Support via the purple chat bubble in the bottom-right corner of your screen for assistance.
