How to upgrade kubuntu 16.04 -> KDE neon

This worked for me and might not work for your.

Try it at your own risk!

Add the neon repositories and install the neon desktop

$ wget -qO - 'http://archive.neon.kde.org/public.key' | sudo apt-key add -
$ sudo apt-add-repository http://archive.neon.kde.org/user
$ sudo apt-get update
$ sudo apt-get install neon-desktop

Upgrade everything. Repeat if necessary, until everything is really up to date and you have no held-back packages.

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade

Works for me, thank you very much!

sudo apt-get install neon-desktop

Is it necessary? What does it bring extra?

Thanks buddy, though this line was very important "Upgrade everything. Repeat if necessary, until everything is really up to date and you have no held-back packages", had a tough time upgrading it, thanks by the way!

If anyone stumbles upon this: DO NOT TRY! There is a very high probability it will screw your plasma or sddm just like it did to me.

If it's too late and you already did screw it you could try:

sudo apt-get install --reinstall neon-desktop plasma-desktop plasma-desktop-data sddm xorg xserver-xorg-core xserver-xorg-video-akk && sudo dpkg-reconfigure sddm
Thanks to: http://askubuntu.com/questions/761358/kubuntu-doesnt-work-after-upgrade-to-16-04/761379#761379 for the idea. But still I had to go through more hoops to solve all my problems.

PS: If you want the neon LTS version (which has plasma 5.8.* not 5.9.* as of the time of writing this) then:
sudo apt-add-repository http://archive.neon.kde.org/user/lts
instead of
sudo apt-add-repository http://archive.neon.kde.org/user

This worked great for me. Thank you,

Also tried this from ubuntu gnome 16.04, worked perfectly.
