I'm trying to connect to the corporate VPN from Kubuntu 17.10. I have network-manager-l2tp installed (version 1.2.8). The output I'm getting:

After spending a few hours digging around, I found out what the problem is, and the solution.
The problem:
- Linux no longer supports the 3DES cipher, but many appliances still use it.
- Kubuntu 17.10 is missing phase1 and phase2 algorithm entry fields under IPSec Settings (this is a known bug), which are needed to setup an L2TP/IPSec connection to use 3DES.
The solution:
- Install the latest version of KDE Plasma from the "backports" PPA.
- Reboot, then create a new L2TP/IPSec VPN connection - phase1 and phase2 algorithm entry fields should now be present.
- For the Phase1 Algorithm, enter: 3des-sha1-modp1024!
- For the Phase2 Algorithm, enter: 3des-sha1!
From memory, I did the following:
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt update && sudo apt upgrade
sudo reboot
sudo apt install network-manager-l2tp-gnome
sudo apt install strongswan
sudo apt install libstrongswan-extra-plugins
sudo apt install libcharon-extra-plugins
Reboot, then add L2TP/IPSec as normal. You should now see the Phase1 and Phase2 algorithm textboxes as show in the attached image.
It's important to note that the above steps will not work if you have installed the latest Linux kernel (4.14 or higher, I believe), so it is highly likely that this workaround to get L2TP/IPSec working with the 3DES cipher will not work when the up and coming *Ubuntu 18.04 LTS is released.
I'am use 16.04. I try your recommendations but still missing phase1 and phase2 algorithm entry fields. Can you give me your config from /etc/NetworkManager/system-connections/ ?

I know that this question was in regards to getting L2TP/IPSec working on Kubuntu 17.10. However, 18.04 is out now, and here's how I get L2TP/IPSec working on Kubuntu 18.04:
$ sudo apt install network-manager-l2tp
$ sudo stop xl2tpd.service
$ sudo systemctl disable xl2tpd.service
Messing around with backports is not longer required as the Phase1 algorithms and Phase2 algorithms text-inputs are now included in the default Network Manager.

The kernel 4.14 bug is related to the following commit :
- https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/net/xfrm?h=v4.14.8&id=c9f3f813d462c72dbe412cee6a5cbacf13c4ad5e
That kernel 4.14 commit breaks IPsec transportation mode when a wildcard address is used on the client side as is the case with network-manager-l2tp. The commit was reverted in kernel-4.15-rc1 :
- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/xfrm?h=v4.15-rc1&id=94802151894d482e82c324edf2c658f8e6b96508
Unfortunately the reversion commit reintroduces a stack out-of-bounds bug. We might need to wait for the kernel 4.14 branch to get a fix after kernel 4.15 is released. More details in this netdev linux kernel mailing list thread :
- https://patchwork.ozlabs.org/patch/838470/

sudo apt install libstrongswan-extra-plugins
sudo apt install libcharon-extra-plugins
Reboot, then add L2TP/IPSec as normal. You should now see the Phase1 and Phase2 algorithm textboxes as show in the attached image.
It's important to note that the above steps will not work if you have installed the latest Linux kernel (4.14 or higher, I believe), so it is highly likely that this workaround to get L2TP/IPSec working with the 3DES cipher will not work when the up and coming *Ubuntu 18.04 LTS is released.

I'am use 16.04. I try your recommendations but still missing phase1 and phase2 algorithm entry fields. Can you give me your config from /etc/NetworkManager/system-connections/ ?

I know that this question was in regards to getting L2TP/IPSec working on Kubuntu 17.10. However, 18.04 is out now, and here's how I get L2TP/IPSec working on Kubuntu 18.04:
$ sudo apt install network-manager-l2tp
$ sudo stop xl2tpd.service
$ sudo systemctl disable xl2tpd.service
Messing around with backports is not longer required as the Phase1 algorithms and Phase2 algorithms text-inputs are now included in the default Network Manager.

The kernel 4.14 bug is related to the following commit :
- https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/net/xfrm?h=v4.14.8&id=c9f3f813d462c72dbe412cee6a5cbacf13c4ad5e
That kernel 4.14 commit breaks IPsec transportation mode when a wildcard address is used on the client side as is the case with network-manager-l2tp. The commit was reverted in kernel-4.15-rc1 :
- https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/net/xfrm?h=v4.15-rc1&id=94802151894d482e82c324edf2c658f8e6b96508
Unfortunately the reversion commit reintroduces a stack out-of-bounds bug. We might need to wait for the kernel 4.14 branch to get a fix after kernel 4.15 is released. More details in this netdev linux kernel mailing list thread :
- https://patchwork.ozlabs.org/patch/838470/
