Today I decided to upgrade Kubuntu 17.10 to 18.04 following Kubuntu's official site steps https://help.ubuntu.com/community/BionicUpgrades/Kubuntu. Although I updated the system, the option to upgrade didn't appear in Discover, so following the site's instructions did this: kdesudo "do-release-upgrade -m desktop -f DistUpgradeViewKDE". Everything okay until I reboot... Instead of Kubuntu 18.04 now I have Ubuntu 18.04??!

Does anybody know why this happened?

Edit: I tried changing the desktop environment to Kubuntu using sudo apt-get install kubuntu-desktop but it doesn't recognize the command

"Upgrades from 16.04 LTS will not be enabled until a few days after the 18.04.1 release expected in late July."

I think the option is not enabled yet

I Followed the steps in the release notes and it worked for me.

The upgrade should run uninterrupted. You will need to:

  1. If you have a laptop make sure it is connected to power.
  2. If at all practical, ensure that you are connected to the Internet via a wired connection.
  3. Ensure your current installation is updated using Plasma Discover
  4. Run the release upgrade tool.
  5. Reboot.

Upgrade

If for some reason Discover does not offer you the upgrade to 18.04, then you can open Krunner, or Konsole (or other terminal), and run:

kdesudo "do-release-upgrade -m desktop -f DistUpgradeViewKDE"
  • Allow the upgrade to start, wait (approximately an hour).
  • Remove obsolete packages when asked
  • It will ask you to restart your computer. Ensure you have no unsaved work open and click Restart Now.

What do you mean by "doesn't recognize the command"?

If your Ubuntu 18.04 is working normally and you want to go back to KDE:

~$ sudo apt-get update
~$ sudo apt-get dist-upgrade
~$ sudo apt-get install kubuntu-desktop

(if it says it's already installed, ignore it and go to next command, if it shows some error, post them here)

~$ sudo dpkg-reconfigure sddm

Make sure to select sddm from list and Ok. Now reboot and Plasma should be loaded.

Now continue from KDE Terminal:

~$ sudo apt-get purge ubuntu-desktop
~$ sudo apt-get purge nautilus
~$ sudo apt-get autoremove
~$ sudo apt-get autoclean
