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
