I resolved by installing NetworkManager-l2tp manually.

 

 

And then, add new VPN connection following steps:

  • Go to Settings -> Network -> Add VPN -> Click Layer 2 Tunneling Protocol (L2TP).
  • Enter Connection name
  • Click VPN tab
  • Enter Gateway, Username, Password
  • Click IPsec Settings
  • Check Enable IPsec tunnel to L2TP host
  • Enter Pre-shared Key
  • Click Save

 

After that, if VPN connection is failed after configured correctly, then it could be an issue with an issue with 3DES cipher setting. Try this step

  • Go to Settings -> Network -> Add VPN -> Click Layer 2 Tunneling Protocol (L2TP).
  • Edit VPN connection that you just created
  • Click VPN tab
  • Click IPSec Settings
  • Enter Phase1 Algorithms as 3des-sha1-modp1024!
  • Enter Phase2 Algorithms as 3des-sha1!
  • Click OK
  • Click Save

 

Try again.
