Adjust to taste as needed. The image has a fallback cloud-init datasource that configures sudo user `ubuntu` with password `ubuntu`. Alternatively, you can provide a config drive (or tweak the first partitions `/var/lib/cloud/seed/nocloud/*` files) to setup anything else using cloud-init. For example ssh keys, disabling interactive login, and so on. See https://cloudinit.readthedocs.io/en/latest  are available at https://cdimage.ubuntu.com/releases/23.04/release/.

=== Server Install Image ===

If you want to install Ubuntu on a disk drive, use the server install image.

 * An Ubuntu 23.10 (Mantic Minotaur) [[https://cdimage.ubuntu.com/releases/23.10/release/ubuntu-23.10-live-server-riscv64.img.gz|server install image]] is available at https://cdimage.ubuntu.com/releases/23.10/release/

 * A Ubuntu 23.04 (Lunar Lobster) server install image supporting the [[RISC-V/SiFive HiFive Unmatched | SiFive HiFive Unmatched]] board and [[RISC-V/QEMU | QEMU]] is available at https://cdimage.ubuntu.com/releases/23.04/release/.


 * A Ubuntu 22.04.3 (Jammy Jellyfish) server install image supporting the [[RISC-V/SiFive HiFive Unmatched | SiFive HiFive Unmatched]] board and [[RISC-V/QEMU | QEMU]] is available at https://cdimage.ubuntu.com/releases/22.04.3/release/.

A tutorial is available at https://ubuntu.com/tutorials/install-ubuntu-server.

A description of the installation process is also available at https://discourse.ubuntu.com/t/ubuntu-installation-on-the-sifive-hifive-unmatched-board-using-a-server-install-image/27804.

=== Desktop ===

We currently don't provide a desktop image for RISC-V. But you can install package ubuntu-desktop to get a GNOME desktop. As of 2022 due to performance restrictions the only hardware usable for a desktop is the SiFive HiFive Unmatched board.

== Forums ==

You can discuss Ubuntu on RISC-V over at the [[https://discourse.ubuntu.com/c/server/17|Ubuntu Server forums]].

Ubuntu provides the riscv64 architecture for the RISC-V platform since the release of Ubuntu 20.04 LTS.
