The official flavour of Ubuntu using KDE. The default desktop environment is KDE Plasma Desktop.
Xenial Xerus (16.04)
- 5 GB of free disk space
- other requirements are similar to the following
Bionic Beaver (18.04)
- 1 GHz processor
- 512 MB of system memory (RAM)
- 8 GB of free disk space
- VGA capable of 1024x768 screen resolution
The minimum requirements were last mentioned in Kubuntu 8.04 news announcement, then merely copied from Ubuntu 12.04 release note and has since deprecated, and not found at elsewhere. The minimum requirements for newer release is unofficial and subject to testing on real hardware or in a virtual machine (VM). Kubuntu has varying requirements on VM.
Xenial Xerus (16.04) on VM: Requires at least 1 GB RAM, 10 GB fixed-size Virtual Disk Image, 128 MB video memory. Selecting "Try Kubuntu" or "Install Kubuntu" does not matter. Live session will takes time to load; If virtual machine has stopped responding, do reset and start again. Installation may take longer time. User will see "low disk space warning" during installation but will succeed.
Bionic Beaver (18.04) on VM: Requires VT-x/AMD-V hardware acceleration, regardless of 32-bit or 64-bit ISO image. Requires at least 9 GB fixed-size Virtual Disk Image. With 512 MB RAM, choose either "Try Kubuntu" or "Install Kubuntu"; otherwise, running the installer from desktop will not work as expected. With 768 MB RAM, user can first choose "Try Kubuntu" and later can also run the installer from the live desktop.
- 1 GHz dual core processor or better
- 2 GB of system memory (RAM)
- 10 GB of free disk space (the more hard disk capacity, the better)
- VGA capable of 1024x768 screen resolution. If desktop effects are desired, a supported GPU is required.
The recommended requirement is based on this poorly cited source on Wikipedia and this partially compatible requirements for Ubuntu 16.04. The amount of system memory and free disk space are similar to the requirements for KDE neon.
Kubuntu has no official system requirements to this revised date.
