New addresses for cloud services: update your gateways

Thanks @kersing the error message has gone. I found a fix on the multitech site that suggests if you add a post-up line in /etc/network/interfaces you can fix the vanishing resolv.conf problem.

Add the post-up line as follows to /etc/network/interfaces:

# Wired interface
auto eth0
iface eth0 inet static
address 192.168.1.50
netmask 255.255.255.0
gateway 192.168.1.254
post-up echo 'nameserver 8.8.8.8' >/etc/resolv.conf

Thanks for your help, now onto the next hurdle in the upgrade...
