Installing Zorin OS

1

Hello

I have been using 17.3 Pro on my laptop as my daily driver now and would like to move one of our systems over to zorin core with a VPN connection.

My 17.3 Pro computer when I use the built in VPN settings it works find and I have no problem getting it to work.

The 18 Core does not,

I go to network and select the + to add vpn select wireguard and fill out all the information. When I add the peer I fight with the interface to copy the data as when I click away the extra box closes.

The 17.3 system doesnt have this extra box that pops up.

Any suggestions would be helpful.

Hi and welcome.

As this is out of my league my search results based on Ubuntu 24.04 (as that is what Zorin 18 is a fork of) in Brave A.I. via Mojeek gives:

" Ubuntu 24.04 WireGuard Configuration Issues and Fixes

Ubuntu 24.04 includes native WireGuard support in the GNOME Network Manager GUI, but users have reported several configuration issues:

  • GUI Import Limitations : The Network Manager GUI fails to import WireGuard .conf files if the filename (including extension) exceeds 20 characters . This is a known bug tracked in Launchpad (Bug #2064320).
    Fix : Rename the configuration file to a shorter name (e.g., wg.conf ) before importing.
  • Missing or Incorrect AllowedIPs : Ensure the AllowedIPs line in your config is set to 0.0.0.0/0 to route all traffic through the tunnel.
    Example :
AllowedIPs = 0.0.0.0/0
  • DNS Leaks : Ubuntu 24.04 fixed DNS leakage when switching networks, but IPv6 leakage remains unresolved .
    Fix : Disable IPv6 at boot by adding ipv6.disable=1 to /etc/default/grub and running sudo update-grub .
  • Alternative: Use nmcli for Reliable Setup
    If GUI import fails, use the command line:
sudo nmcli connection import type wireguard file /path/to/your/wg0.conf

This method reliably imports configs and shows up in the GUI.

  • Verify Configuration : After setup, check the connection with:
nmcli connection show "Your-Connection-Name"
wg show
  • Server-Side Check : Ensure your WireGuard server allows traffic on UDP port 51820 and has proper AllowedIPs , Endpoint , and DNS settings.
