The server install image allows you to install Ubuntu-Server permanently on a computer for use as a server. It will not install a graphical user interface.

RISC-V server install image

For RISC-V computers. Requires copying your own first stage bootloader (like u-boot) and relevant DTBs onto the image before usage on real hardware (like the SiFive HiFive Unmatched).
Warning: This image is oversized (which is a bug) and will not fit onto a standard 703MiB CD. However, you may still test it using a DVD, a USB drive, or a virtual machine.

Netboot tarball

The netboot tarball contains files needed to boot the Ubuntu-Server installer over the network.

64-bit ARM (ARMv8/AArch64) netboot tarball

For ARM hardware for which we do not ship preinstalled images, see ARM/Server/Install for detailed installation information.
