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-upgradeSee: 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-upgradeUpgrading from Ubuntu 16.04 LTS or 17.10
