Installation
UH VPN Server software demands the following prerequisites:
OS: Ubuntu 20.04 (focal), 22.04 (jammy) or 24.04 (noble)
RAM: 100MB (1GB preferable)
Network: Machine accessible either by public IP address, hostname or dynamic DNS.
The first step is to install the required dependencies:
sudo apt-get update
sudo apt-get install software-properties-common
Then it’s time to add Ultra Horizon’s package archive to the system sources:
sudo add-apt-repository ppa:ultrahorizon/ppa

A prompt will then display information about the repository, accept this, then download the package information from this newly added archive:
sudo apt-get update
Once this is done, UH VPN Server software can now be downloaded through the apt package manager.
sudo apt-get install uh-vpn-server
Once installed check that the UH VPN Service is running:
sudo service uh-vpn-server status
The output should say active (running) as depicted below:

If one desires UH VPN Server to start at boot, issue the following command:
sudo systemctl enable uh-vpn-server
