Installation

Ubuntu

Open Terminal and proceed with following instructions:

1. (Optionally) Upgrade your system to latest packages including latest available kernel by running apt-get full-upgrade. After kernel upgrade reboot is required.
2. Ensure that you have source repositories configured for APT - run vi /etc/apt/sources.list and make sure that there is at least one line starting with deb-src is present and uncommented.
3. Install pre-requisites - run sudo apt install -y software-properties-common python3-launchpadlib gnupg2 linux-headers-$(uname -r).
4. Run sudo add-apt-repository ppa:amnezia/ppa.
5. Finally execute sudo apt-get install -y amneziawg.

Debian

Open Terminal and do next steps:

1. (Optionally) Upgrade your system to latest packages including latest available kernel by running apt-get full-upgrade. After kernel upgrade reboot is required.
2. Ensure that you have source repositories configured for APT - run vi /etc/apt/sources.list and make sure that there is at least one line starting with deb-src is present and uncommented.
3. Execute following commands:

   sudo apt install -y software-properties-common python3-launchpadlib gnupg2 linux-headers-$(uname -r)
   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 57290828
   echo "deb https://ppa.launchpadcontent.net/amnezia/ppa/ubuntu focal main" | sudo tee -a /etc/apt/sources.list
   echo "deb-src https://ppa.launchpadcontent.net/amnezia/ppa/ubuntu focal main" | sudo tee -a /etc/apt/sources.list
   sudo apt-get update
   sudo apt-get install -y amneziawg

Linux Mint

Open Software Sources and make sure that Source code repositories (under Optional Sources) are enabled.

Proceed to PPAs section and add ppa:amnezia/ppa PPA repository, after that save configuration and rebuild apt cache.

After that, open Terminal and run:

sudo apt-get install -y amneziawg

RHEL/CentOS/SUSE/Fedora Core

If you use release that doesn't have DKMS support out of the box, you may need to install EPEL first.

Open Terminal and run:

sudo dnf copr enable amneziavpn/amneziawg
sudo dnf install amneziawg-dkms amneziawg-tools

Before installation it is strictly recommended to upgrade your system kernel to the latest available version and perform the reboot afterwards.

Manual build

You may need to install kernel headers and/or build essentials packages before running following steps.

1. In Terminal:

   git clone https://github.com/amnezia-vpn/amneziawg-linux-kernel-module.git
   cd amneziawg-linux-kernel-module/src

2. Now, if you run modern Linux with kernel version 5.6+, you need to download your kernel's source from anywhere possible and link resulting tree to kernel symlink:

   ln -s /path/to/kernel/source kernel

   Please note to find and provide full kernel sourcetree, not only headers. If you run on legacy kernel (<5.6), you do not need to perform this step.

3. Now perform build and installation:

   make
   sudo make install

   Or on a capable system you may want to use DKMS for this:

   sudo make dkms-install
   sudo dkms add -m amneziawg -v 1.0.0
   sudo dkms build -m amneziawg -v 1.0.0
   sudo dkms install -m amneziawg -v 1.0.0

Configuration

[!IMPORTANT] All parameters should be the same between Client and Server, except Jc - it can vary.

• Jc — 1 ≤ Jc ≤ 128; recommended range is from 3 to 10 inclusive
• Jmin — Jmin < Jmax; recommended value is 50
• Jmax — Jmin < Jmax ≤ 1280; recommended value is 1000
• S1 — S1 < 1280; S1 + 56 ≠ S2; recommended range is from 15 to 150 inclusive
• S2 — S2 < 1280; recommended range is from 15 to 150 inclusive
• H1/H2/H3/H4 — must be unique among each other; recommended range is from 5 to 2147483647 inclusive

Troubleshooting

[!TIP] Please check Ubuntu Server documentation for more troubleshooting steps.

Enable debug logging

To get more details, you can enable the dynamic debug feature for the module:

echo "module amneziawg +p" | sudo tee /sys/kernel/debug/dynamic_debug/control

This will log messages to dmesg, which can be watched live with:

dmesg -wT

Low space on /tmp filesystem

Most installation instructions above assume that you have enough space in system's /tmp partition (as setup script needs to manipulate with kernel's sourcetree which is pretty huge).

If you can not afford enough space in your /tmp, you may override temporary dir by setting AWG_TEMP_DIR environment variable before the installation:

export AWG_TEMP_DIR="/home/ubuntu/tmp"

This setting should persist for future and will not require repeating.

Kernel sourcetree could not be found automatically

In some rare cases, setup script may not find your kernel's sourcetree automatically. You may find appropriate sources by yourself then and link them to DKMS module sources, e.g.

ln -s /path/to/your/kernel/sources /usr/src/amneziawg-1.0.0/kernel

Reinstall the package thereafter and you should get everything working.

Should you upgrade your kernel in the future, please remember that you may also need refresh sourcetree and update symlinks.
