Upgrading from LTS releases such as 14.04 to another LTS release are direct and don't include any interim release upgrades. Going from 14.10 to 16.04 would require going first to 15.04 then 15.10 and finally 16.04. I did an upgrade from 12.04 to 14.04 which took over 3 hours while a new install took < 30 minutes so a new install in your case after backing up will be simpler. Ubuntu link on upgrades below.

BTW itts works the only thing its got to my way in the end to connect to the internet is that there is no resolv.conf file

Glad to hear it works.
