Ubuntu is distributed on four types of images described below.
Server install image
The server install image allows you to install Ubuntu permanently on a computer for use as a server. It will not install a graphical user interface.
64-bit ARM (ARMv8/AArch64) server install image
For 64-bit ARMv8 processors and above.
PowerPC64 Little-Endian server install imageFor POWER8 and POWER9 Little-Endian systems, especially the "LC" Linux-only servers.
IBM System z server install imageFor IBM System z series mainframes, such as IBM LinuxONE.
Preinstalled desktop image
The preinstalled-desktop image allows you to unpack a preinstalled version of Ubuntu onto a target device.
Raspberry Pi Generic (64-bit ARM) preinstalled desktop image
For modern Raspberry Pi boards (Pi 2, Pi 3 and Pi 4).
Preinstalled server image
The preinstalled-server image allows you to unpack a preinstalled version of Ubuntu onto a target device.
Raspberry Pi Generic (Hard-Float) preinstalled server image
For modern Raspberry Pi boards (Pi 2, Pi 3 and Pi 4).
Raspberry Pi Generic (64-bit ARM) preinstalled server imageFor modern Raspberry Pi boards (Pi 2, Pi 3 and Pi 4).
RISC-V for SiFive HiFive Unleashed preinstalled server imageFor RISC-V computers, with support for SiFive HiFive Unleashed and QEMU.
RISC-V for SiFive HiFive Unmatched preinstalled server imageFor RISC-V computers, with support for SiFive HiFive Unmatched and QEMU.
For ARM hardware for which we do not ship preinstalled images, see ARM/Server/Install for detailed installation information.
A full list of available files, including BitTorrent files, can be found below.
If you need help burning these images to disk, see the Image Burning Guide.
