Does anyone have experience with connecting to an Algo VPN on a Ubuntu 16.04 client (running Gnome)?

Would really love to know how to best do this, thanks!

I tried a little but now i get some problem setting the server, seeing this using strongswan or wireguard you should.
And this is what says https://github.com/trailofbits/algo/blob/master/docs/client-linux.md :

(Gnome) Network Manager configuration

In this example we'll assume the IP of our Algo VPN server is 1.2.3.4 and the user we created is user-name.

Go to Settings > Network
Add a new Network (+ bottom left of the window)
Select IPsec/IKEv2 (strongswan)
Fill out the options:
 Name: your choice, e.g.: ikev2-1.2.3.4
 Gateway:
 Address: IP of the Algo VPN server, e.g: 1.2.3.4
 Certificate: cacert.pem found at /path/to/algo/configs/1.2.3.4/cacert.pem
 Client:
 Authentication: Certificate/Private key
 Certificate: user-name.crt found at /path/to/algo/configs/1.2.3.4/pki/certs/user-name.crt
 Private key: user-name.key found at /path/to/algo/configs/1.2.3.4/pki/private/user-name.key
 Options:
 Check Request an inner IP address, connection will fail without this option
 Optionally check Enforce UDP encapsulation
 Optionally check Use IP compression
 For the later 2 options, hover to option in the settings to see a description
 Cipher proposal:
 Check Enable custom proposals
 IKE: aes256gcm16-prfsha512-ecp384,aes256-sha2_512-prfsha512-ecp384,aes256-sha2_384-prfsha384-ecp384
 ESP: aes256gcm16-ecp384,aes256-sha2_512-prfsha512-ecp384
Apply and turn the connection on, you should now be connected
