Kubuntu does not update

[JoseMarcos]

Hello, everyone. My name is Jose Marcos and I'm from Brazil. I'm new to Linux and I've been using Kubuntu for 8 months. I am trying to upgrade my Kubuntu to version 19.04 but does not update. I tried with the commands below:

sudo add-apt-repository PPA: Kubuntu-PPA/Backports
sudo apt update
sudo apt-get dist-Upgrade

But you haven't updated. How do I upgrade? See below for the version of my Kubuntu.

Thank you and excuse my English.

You can't by default upgrade from LTS to a non-LTS release of Ubuntu. You can enable this, but you will have upgrade from 18.04 to 18.10 first, then 19.04, you can't skip a release.

apt-get dist-upgrade is very confusingly named and it is not a "distribution" upgrade. This has confused many, including myself in my early Kubuntu days. (I prefer sudo apt full-upgrade which does the same as apt-get dist-upgrade.)

After fixing the LTS only restriction that claydoh referred to, if you want to use the command line it's

sudo do-release-upgrade

Thank you all very much. I was able to install. I couldn't have done it without your help.
