Hi Eric and Łukasz,

I uninstalled existing xl2tpd from test PPA on xenial and bionic before
installing xl2tpd from respective proposed repository.

On xenial I installed and tested xl2tpd_1.3.6+dfsg-
4ubuntu0.16.04.2_amd64.deb and can confirm I'm able to establish
L2TP/IPsec VPN connection with following kernels :

* kernel 4.4.0-124-generic.
* kernel 4.13.0-36-generic.
* kernel 4.15.0-29-generic.

Similarly on bionic with xl2tpd_1.3.10-1ubuntu1_amd64.deb, I can confirm VPN connection with following kernels : 
* kernel 4.13.0-36-generic.
* kernel 4.15.0-29-generic.

I've changed verification-needed-bionic and verification-needed-xenial
to verification-done-bionic and verification-done-xenial respectively.

I didn't change the verification-needed tag, but guess I should have.

Bug description:
  [Impact]

  Kernel 4.15 breaks xl2tpd, please see following upstream issue for more details :
     https://github.com/xelerance/xl2tpd/issues/147

  The following commit/patch fixes the issue:
    https://github.com/xelerance/xl2tpd/commit/9c2cd4933478a83075df5b10f24af7589e90abc3.patch

  As Ubuntu 18.04 (Bionic Beaver) is no longer accepting Debian
  packages, I'm guessing then that the patch would need to be added and
  applied to the existing xl2tpd-1.3.10-1 package.

  The linux-image kernel package on Ubuntu 18.04 is currently linux-
  image-4.15.0-13

  [Test Case]

  * apt install network-manager-l2tp-gnome
  * Add new VPN connection via network manager
  * establish vpn connection

  [Regression Potential]

  * For Bionic, there is none. The xl2tpd daemon does not work without the patch on the standard bionic kernel.
  * For Xenial w/ the 4.15 HWE kernel there is no risk.
  * For Xenial w/ the stock 4.4 kernel there is minimal risk as the code is pulling values that are not valid on the 4.4 kernel by default.

  Note that a test pkg (Pre-SRU) has been tested for both Bionic and
  Xenial by a user affected by this problem and the package has been
  proven to work as expected on the different supported Ubuntu kernel
  series (v4.4, v4.13, v4.15).

  For more details, please have a look at comment #17 and #23.
