In Ubuntu 19.10, I was able to successfully add one L2TP VPN that has been working great since installing 19.10.
However, upon adding an additional L2TP VPN, it not only didn't work, but it also corrupted the first L2TP VPN that was "already added and working".
This corruption is so bad, that even when I remove all VPN profiles, reboot, and add one again, it still doesn't work. At the same time, I can add the very same L2TP VPN configuration to a virtual machine of 19.10, and the L2TP VPN works fine.
I've submitted bugs regarding this here:
You can see the syslog details of a failed connection attempt at the links above.
Short of reinstalling Ubuntu 19.10, how might I undo this corruption caused by adding a 2nd L2TP VPN profile? Perhaps there are some files I can go delete to make things fresh. Please advise.
