Hi @prashantpawar723,

This is really weird. Is this a new droplet or some changes has been made to it?

Additionally, did you make sure to install the following prior to trying the command:

sudo apt install strongswan strongswan-pki libcharon-extra-plugins libcharon-extauth-plugins libstrongswan-extra-plugins

Same problem here. Brand new droplet (Basic, Amsterdam 3)

Was following these instructions

A virtual private network, or VPN, allows you to securely encrypt traffic as it travels through untrusted networks, such as those at the coffee shop, a conference, or an airport. In this tutorial, you'll set up an IKEv2 VPN server using [StrongSwan](https://www.strongswan.org/) on an Ubuntu 20.04 server and learn how to connect to it with Windows, macOS, Ubuntu, iOS, and Android clients.
