I’ve installed ubuntu 17.04 and I want to upgrade it to 18.04. When I tried to do:
I got a message saying
An upgrade from 'zesty' to 'bionic' is not supported with this tool. Need inputs to proceed on this.

This was not properly explained anywhere, here is what you need to do (or how I did it):
Upgrade to 17.04 to 17.10:
Unable to upgrade from ubuntu 17.04 to 17.10
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak #to be safe sudo sed -i -re 's/old-releases.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list sudo sed -i -re 's/zesty/artful/g' /etc/apt/sources.list sudo apt update sudo apt dist-upgrade sudo apt autoremove
(Links says to use aptitude instead of apt-get)
Upgrade from 17.10 to 18.04: EOLUpgrades
Replace everything in /etc/apt/sources.list with this:
## EOL upgrade sources.list # Required deb http://old-releases.ubuntu.com/ubuntu/ artful main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ artful-updates main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ artful-security main restricted universe multiverse # Optional #deb http://old-releases.ubuntu.com/ubuntu/ artful-backports main restricted universe multiverse
Then run the upgrade:
apt-get update apt-get dist-upgrade do-release-upgrade
Do what it says when asked and wait for it to finish and you should be done.
# Upgrade from 17.04 to 17.10 # backup current sources file (just in case) sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak # change version codename from 'zesty' to 'artful' sudo sed -i -re 's/zesty/artful/g' /etc/apt/sources.list # 17.10 has reached it's end of life # so we fetch from 'old-releases.ubuntu.com' sudo sed -i -re 's/archive.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list sudo apt update sudo apt dist-upgrade sudo apt autoremove
# Upgrade from 17.10 to 18.04 LTS # change version codename from 'artful' to 'bionic' sudo sed -i -re 's/artful/bionic/g' /etc/apt/sources.list # 18.04 has NOT reached it's end of life yet (due in 2028) # so we fetch from 'archive.ubuntu.com' sudo sed -i -re 's/old-releases.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list sudo apt update sudo apt dist-upgrade sudo apt autoremove
