In this video I show a method of changing from one Ubuntu flavour to another. Installing Ubuntu Flavours https://ubuntu.com/download/flavours For example, to replace Ubuntu with Kubuntu, you would use the following Terminal command: sudo apt install kubuntu-desktop Alternatively, for Lubuntu it would be: sudo apt install lubuntu-desktop For Ubuntu Budgie: sudo apt install ubuntu-budgie-desktop For Ubuntu Kylin: sudo apt install ubuntukylin-desktop For Ubuntu Mate: sudo apt install ubuntu-mate-desktop And finally, for Xubuntu: sudo apt install xubuntu-desktop Depending on the flavour you are installing, you may get a prompt to replace a display manager, so choose the recommended one for the desktop environment. Once done, reboot your system. Remove Redundant Software For example, to remove left over Ubuntu software, you can use the following Terminal command: sudo apt remove ubuntu-desktop ubuntu-software software-properties-gtk nautilus update-manager gnome-system-monitor #ubuntu #kubuntu #flavours
