Select an image
Ubuntu-Server is distributed on three types of images described below.
Server install image
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.
Choose this if you have a computer based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). Choose this if you are at all unsure.
64-bit ARM (ARMv8/AArch64) server install imageFor 64-bit ARMv8 processors and above.
PowerPC64 Little-Endian server install imageFor POWER9 and POWER10 Little-Endian systems.
RISC-V server install imageFor 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).
IBM System z server install imageFor IBM System z series mainframes, such as IBM LinuxONE.
Netboot tarball
The netboot tarball contains files needed to boot the Ubuntu-Server installer over the network.
Choose this if you have a computer based on the AMD64 or EM64T architecture (e.g., Athlon64, Opteron, EM64T Xeon, Core 2). Choose this if you are at all unsure.
64-bit ARM (ARMv8/AArch64) netboot tarballFor 64-bit ARMv8 processors and above.
PowerPC64 Little-Endian netboot tarballFor POWER9 and POWER10 Little-Endian systems.
RISC-V netboot tarballFor 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).
IBM System z netboot tarballFor IBM System z series mainframes, such as IBM LinuxONE.
For ARM hardware for which we do not ship preinstalled images, see ARM/Server/Install for detailed installation information.
