  • Even I format and reinstall ubuntu 20.04 without any other software, only required update installed, It is not working. – Nitish kumar Dec 19 '20 at 16:14

    Viewing the output of `sudo journalctl --unit=NetworkManager` after a failed connection would be useful to determine what is going wrong. – Douglas Kosovic Jan 18 '21 at 21:51

The package network-manager-l2tp is required.

You may have to install it:

sudo apt install network-manager-l2tp

I hope it helps

I was facing this myself in Ubuntu 20.04 and 21.04, and a simple one-liner solved all requirements necessary for my L2TP/IPsec setup to work properly:

sudo apt install --install-suggests network-manager-l2tp-gnome

This installs all packages mentioned in the previous answers, too. Endpoint to connect to is a Ubiquiti EdgeRouter ERLite-3.

Check your log i suspect you may need to install these as well if the dependancy is not met:

 sudo apt install libstrongswan-standard-plugins libstrongswan-extra-plugins
