In /etc/sysctl.conf?  Are you saying that if you set this to 1 it would be
reset upon reboot back to 0?

On my 16.04 system, they are the same file.  99-sysctl.conf is a symlink to
../sysctl.conf.

Then there was the suggestion to use the GUI and disable ipv6 from there.

Here's an article that seems to suggest that for 18.04 systems, the
necessary solution is to actually achieve it by passing a kernel parameter
on boot:

Hmm.  Log in remotely how?  What method of logging in remotely are you
referring to?  This would have to be worked through to solve the problem.
I would suggest initially checking the Ethernet interface as it is with
your Network Manager based settings using '/sbin/ifconfig -a' and then
checking it again after applying settings in /etc/network/interfaces, with
the same command to make sure it's getting set-up correctly.

Cheers, Ian
