How to upgrade from Ubuntu 18.04 or Ubuntu 18.10

Ubuntu 19.04 daily build ISO can be downloaded from this link and you can install it on a physical machine, on a container or on a virtual machine. If you have an existing Ubuntu machine with 18.04 or 18.10 releases on board, you can upgrade to the new Ubuntu 19.04 ‘Disco Dingo’ directly from command line terminal.

Here the procedure to upgrade your system to the new Ubuntu 19.04 release. First, open a terminal window and fully update your current release:

$ sudo apt update
$ sudo apt upgrade
$ sudo apt dist-upgrade
$ sudo apt autoremove

Check the file /etc/update-manager/release-upgrades.

Prompt=normal offers upgrades from any release to a newer release; Prompt=never never offers release upgrades; Prompt=lts only offers upgrades from LTS to LTS. You need root privileges to edit this file.

So, first, open and edit /etc/update-manager/release-upgrades file:

$ sudo vi /etc/update-manager/release-upgrades

Set Prompt=normal to avoid ‘No new release found’ message and save the file with :wq.

Update your system with the following command:

$ sudo do-release-upgrade

If you are on Ubuntu 18.10, you will be upgraded to Ubuntu 19.04, but if you are on the Ubuntu 18.04 release, you will be upgraded to Ubuntu 18.10 only, so you should repeat the process to perform the upgrade to the latest Ubuntu 19.04.

Additional note: if you’re performing the upgrade process before the Ubuntu 19.04 ‘Disco Dingo’ release date, you should use the -d option to perform the update.

$ sudo do-release-upgrade -d

Remember that if you try to use the -d option directly from Ubuntu 18.04, you’ll get this message:

$ sudo do-release-upgrade -d #From Ubuntu 18.04
