The variable to define which interface the dhcpd runs on has changed,
but unfortunately the contents of /etc/default/isc-dhcp-server were not
adapted at the same time.

You need to change

INTERFACES="..."

to

INTERFACESv4="..."

to be able to start the DHCP server again.

And I guess this bug is not just important but of severity "grave".
