The actual programmer of this module says we need to upgrade-software-
version.
1)
https://gitlab.gnome.org/GNOME/gnome-control-center/issues/746#note_634394
2)
https://github.com/nm-l2tp/NetworkManager-l2tp/issues/112#issuecomment-547218557
He believes that this issue is fixed in NetworkManager-l2tp 1.2.12 and later.
Who at Ubuntu can accomplish getting this upgraded in 19.10 instead of
having to wait for 20.04?
Ideally, the upgrade should just be provided via the standard Ubuntu Update GUI
or CLI:
sudo apt update ; sudo apt upgrade
At this point, upstream has already addressed this bug in a later
version, and it is now up to Ubuntu to upgrade the package in the
repositories.
What is the likelihood that this will be upgraded in Upgraded 19.10?

Title:
Additional L2TP VPN Breaks First VPN

Status in L2TP over IPsec VPN Manager:

Status in NetworkManager:

Status in strongSwan:

Status in gnome-control-center package in Ubuntu:

Bug description:
When I add only one L2TP VPN profile to gnome-control-center's Network
> VPN settings, it works fine.
However, if I add a 2nd L2TP VPN, the 2nd L2TP VPN, not only doesn't
work, but it corrupts the first L2TP VPN so that it too stops working.
Furthermore, if I remove 2nd L2TP VPN profile (that corrupted the
first L2TP VPN) this does NOT repair the corruption to the first L2TP
VPN, it remains corrupted.
Additionally, removing all VPN profiles and re-adding the first one
back, doesn't repair the corruption. Rebooting and adding them back
doesn't work either.
The only thing that works, that I've found, is completely reinstalling
Ubuntu 19.10. Please advise better workarounds than reinstalling.
In case it matters, these additional packages were also required for
my initial VPN setup:
sudo apt-get install -y network-manager-l2tp network-manager-l2tp-
gnome strongswan
Here's what's in the syslog on a failed VPN Connection attempt:
