  1. The package network-manager-l2tp is required.

    You may have to install it:

    sudo apt install network-manager-l2tp

    I hope it helps

  2. 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

  3. 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.
