I have been trying to upgrading my Ubuntu server from the following :
Distributor ID: Ubuntu Description: Ubuntu 16.04.7 LTS Release: 16.04 Codename: xenial to Ubuntu 18.04 LTS. I have updated the system
$ sudo apt update && sudo apt upgrade Get:1 xenial InRelease [247 kB] Get:2 xenial-updates InRelease [109 kB] Get:3 xenial-backports InRelease [107 kB] Get:4 xenial/main amd64 Packages [1,201 kB] Get:5 xenial/main i386 Packages [1,196 kB] Hit:6 xenial InRelease Get:7 xenial/main Translation-en [568 kB] Get:8 xenial/restricted amd64 Packages [8,344 B] Fetched 29.9 MB in 7s (4,183 kB/s) Reading package lists...

The regualr way to upgrade
To upgrade from lts to lts, edit your /etc/update-manager/release-upgrades with the following line:
Prompt=lts Then run:
sudo do-release-upgrade See: Upgrade policy
The Debian way of upgrading:
sudo sed -i.ORIG 's/xenial/bionic/g' /etc/apt/sources.list sudo mv /etc/apt/sources.list.d/ /etc/apt/ sudo mkdir /etc/apt/sources.list.d/ sudo aptitude update sudo aptitude safe-upgrade sudo aptitude full-upgrade Upgrading from Ubuntu 16.04 LTS or 17.10
Thank you everyone for the assist.
Problem was in :
/etc/update-manager/meta-release # There was a couple lines for some monitoring software removed them and saved and worked perfectly :)
command that assisted , cant remember where i saw it but thank you
export DEBUG_UPDATE_MANGER=true
Hope this helps anyone else that has this problem
