Operating the Server installer
|
||
|
******************************
|
||
|
|
||
|
This document explains how to use the installer in general terms. For a
|
||
|
step-by-step guide through the screens of the installer, you can use our
|
||
|
`screen-by-screen reference guide <https://discourse.ubuntu.com/t/draft-using-the-server-installer-step-by-step/16690>`_.
|
||
|
|
||
|
Get the installer
|
||
|
=================
|
||
|
|
||
|
Installer images are made (approximately) daily and are available from
|
||
|
https://cdimage.ubuntu.com/ubuntu-server/daily-live/current/. These are not
|
||
|
tested as extensively as the images from release day, but they contain the
|
||
|
latest packages and installer, so fewer updates will be required during or
|
||
|
after installation.
|
||
|
|
||
|
You can download the server installer for amd64 from
|
||
|
https://ubuntu.com/download/server and other architectures from
|
||
|
http://cdimage.ubuntu.com/releases/20.04/release/.
|
||
|
|
||
|
Installer UI navigation
|
||
|
=======================
|
||
|
|
||
|
In general, the installer can be used with the :kbd:`up` and :kbd:`down` arrows
|
||
|
and :kbd:`space` or :kbd:`Enter` keys and a little typing.
|
||
|
|
||
|
:kbd:`Tab` and :kbd:`Shift` + :kbd:`Tab` move the focus down and up respectively.
|
||
|
:kbd:`Home` / :kbd:`End` / :kbd:`Page Up` / :kbd:`Page Down` can be used to
|
||
|
navigate through long lists more quickly in the usual way.
|
||
|
|
||
|
Running the installer over serial
|
||
|
=================================
|
||
|
|
||
|
By default, the installer runs on the first virtual terminal, ``tty1``. This
|
||
|
is what is displayed on any connected monitor by default. However, servers do
|
||
|
not always have a monitor. Some out-of-band management systems provide a
|
||
|
remote virtual terminal, but sometimes it is necessary to run the installer on
|
||
|
the serial port. To do this, the kernel command line needs to
|
||
|
`have an appropriate console <https://www.kernel.org/doc/html/latest/admin-guide/serial-console.html>`_
|
||
|
specified on it -- a common value is ``console=ttyS0`` but this is not
|
||
|
something that can be generically documented.
|
||
|
|
||
|
When running on serial, the installer starts in a basic mode that uses only
|
||
|
the ASCII character set and black and white colours. If you are connecting from
|
||
|
a terminal emulator such as gnome-terminal that supports Unicode and rich
|
||
|
colours you can switch to "rich mode" which uses Unicode, colours and supports
|
||
|
many languages.
|
||
|
|
||
|
.. _connect-via-ssh:
|
||
|
|
||
|
Connecting to the installer over SSH
|
||
|
====================================
|
||
|
|
||
|
If the only available terminal is very basic, an alternative is to connect via
|
||
|
SSH. If the network is up by the time the installer starts, instructions are
|
||
|
offered on the initial screen in basic mode. Otherwise, instructions are
|
||
|
available from the help menu once networking is configured.
|
||
|
|
||
|
In addition, connecting via SSH is assumed to be capable of displaying all
|
||
|
Unicode characters, enabling more translations to be used than can be displayed
|
||
|
on a virtual terminal.
|
||
|
|
||
|
Help menu
|
||
|
=========
|
||
|
|
||
|
The help menu is always in the top right of the screen. It contains help --
|
||
|
both general and for the currently displayed screen -- and some general actions.
|
||
|
|
||
|
Switching to a shell prompt
|
||
|
---------------------------
|
||
|
|
||
|
You can switch to a shell at any time by selecting "Enter shell" from the help
|
||
|
menu, or pressing :kbd:`Control` + :kbd:`Z` or :kbd:`F2`.
|
||
|
|
||
|
If you are accessing the installer via ``tty1``, you can also access a shell
|
||
|
by switching to a different virtual terminal (:kbd:`Control` + :kbd:`Alt` +
|
||
|
arrow, or :kbd:`Control` + :kbd:`Alt` + number keys, to move between virtual
|
||
|
terminals).
|
||
|
|
||
|
Global keys
|
||
|
===========
|
||
|
|
||
|
There are some global keys you can press at any time:
