To connect to a Wideguard VPN from your local machine to a remote server using the AmneziaWG configuration file you previously received from the configured server, follow these steps. This guide assumes you are using Ubuntu 22.04. You’ll need to install the WireGuard software, configure it, and initiate the VPN connection. Here’s how to do it:

​
1. Change sources.list on the client’s operation system:

Open a terminal and back up your sources.list: 
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
Edit the File: 
nano /etc/apt/sources.list
Uncomment deb-src Lines: Remove the # from the beginning of any deb-src lines you want to activate. 
#Example sources.list file for Ubuntu 22.04
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.

deb-src http://archive.ubuntu.com/ubuntu jammy main restricted

Save and Exit.

​
2. Upgrade the System

apt update && apt upgrade && apt-get full-upgrade && apt install resolvconf

​
3. Install AmneziaWG on Ubuntu 22.04

apt install -y software-properties-common python3-launchpadlib gnupg2 linux-headers-$(uname -r)

add-apt-repository ppa:amnezia/ppa

apt-get install -y amneziawg
Check the availability of all necessary drivers in the system: 
lsmod | grep amnezia
If the command doesn’t show any outputs execute this command: 
modprobe amneziawg && lsmod | grep amnezia

​
4. Copy AmneziaWG client config to Linux (Ubuntu)

Include the command: 
scp [username]@[server-ip-address]:/root/awg/wg-client1.conf /etc/amnezia/amneziawg/
Where:
  • username - the username of the server
  • server-ip-address - the IP address of the server
  • /root/awg/ - directory where located an amneziawg client config files
  • wg-client1.conf - amneziawg config file
  • /etc/amnezia/amneziawg/ - the local directory on your Linux machine

​
5. Get Your Amnezia WireGuard Configuration

The Amnezia wireguard configuration file must be downloaded from VPS. The .conf file, is usually in the following format: 
[Interface]
PrivateKey = kHcPwRvI3FRc4qcE+Fgrln1K1qxQNM3jl4CpPzaYx4o=
#_PublicKey = 7vzU3tVk39Dj+XvjpX3e9yZzDZhfbTZUde2Elju3nRM=
Address = 10.10.8.2/32
DNS = 8.8.8.8
Jc = 120
Jmin = 60
Jmax = 1266
S1 = 11
S2 = 54
H1 = 563549684
H2 = 1544213701
H3 = 529241130
H4 = 981267317

[Peer]
AllowedIPs = 0.0.0.0/5, 8.0.0.0/7, 11.0.0.0/8, 12.0.0.0/6, 16.0.0.0/4, 32.0.0.0/3, 64.0.0.0/2, 128.0.0.0/3, 160.0.0.0/5, 168.0.0.0/6, 172.0.0.0/12, 172.32.0.0/11, 172.64.0.0/10, 172.128.0.0/9, 173.0.0.0/8, 174.0.0.0/7, 176.0.0.0/4, 192.0.0.0/9, 192.128.0.0/11, 192.160.0.0/13, 192.169.0.0/16, 192.170.0.0/15, 192.172.0.0/14, 192.176.0.0/12, 192.192.0.0/10, 193.0.0.0/8, 194.0.0.0/7, 196.0.0.0/6, 200.0.0.0/5, 208.0.0.0/4, 8.8.8.8/32
Endpoint = VPS_REMOTE_IP:54666
PersistentKeepalive = 60
PublicKey = 7gExcFjYZ6rR5nU7F3xzrDQchtGu4OCxEwGjSlRGwnE=
Save this file with a .conf extension, e.g., wg0.conf.

​
6. Move Configuration to AmneziaWG Directory

Move your configuration file to AmneziaWG’s directory, where wg-client1.conf this is a client config that was previously downloaded from the server: 
sudo mv /etc/amnezia/amneziawg/wg-client1.conf /etc/amnezia/amneziawg/wg0.conf
Ensure the file permissions are restricted to prevent unauthorized access: 
sudo chmod 600 /etc/amnezia/amneziawg/wg0.conf

​
7. Start the WireGuard VPN Connection

To start the VPN connection using the configuration file, run the following command: 
sudo awg-quick up wg0
If everything is configured properly, you’ll be connected to the WireGuard VPN.

​
8. Verify the Connection

To check if the connection is active, use: 
awg show
ip
This command shows details about the active WireGuard connection, such as the interface name, peer details, and data transfer statistics.

​
9. Disconnect from the VPN

To stop the VPN connection, use: 
sudo awg-quick down wg0

​
10. Optionally Enable WireGuard on Boot

If you want the VPN to start automatically on boot, you can enable it with: 
sudo systemctl enable awg-quick@wg0
To disable it from starting on boot, use: 
sudo systemctl disable awg-quick@wg0

​
Troubleshooting Tips:

  • Ensure that your private key, public key, and endpoint details in the configuration are correct.
  • If you face any connection issues, check the system logs for more detailed error messages: 
sudo journalctl -xe
Following these steps, you should be able to connect to AmneziaWG on Ubuntu. Links:
