UBIQUITY(8)		Ubuntu System Manager's Manual		   UBIQUITY(8)

NAME
     ubiquity — install Ubuntu from a live CD

SYNOPSIS
     ubiquity [--desktop file] [--debug] [--pdb] [--cdebconf] [--automatic]
	      [--only] [--query] [frontend]

DESCRIPTION
     ubiquity is a graphical installer for Ubuntu, written largely in Python,
     using debian-installer (d-i) as a backend for many of its functions.  It
     is normally invoked from a desktop icon, and presents a "wizard"-style
     graphical user interface.	ubiquity must be run as root, and will esca‐
     late privileges for itself using gksudo, kdesu, kdesudo, or sudo as
     appropriate.

     ubiquity has multiple frontends, including one written using GTK+
     (gtk_ui) and one written for KDE (kde_ui).	 The first non-option argu‐
     ment, if any, is interpreted as the name of the frontend to use.

     The following options are available:

     --desktop file
	   This option is passed through to gksudo to provide a better
	   description for its privilege-escalation message.  It is only rele‐
	   vant when using the gtk_ui frontend.

     -d, --debug
	   Run in debugging mode, sending verbose information to
	   /var/log/installer/debug that may be useful to developers.  (The
	   /var/log/syslog file is usually required in any case, along with
	   /var/log/partman in the case of problems related to partitioning.)
	   Note that passwords will be logged in debugging mode!

     --pdb
	   Drop into the Python debugger in the event of a crash.  Only effec‐
	   tive if ubiquity is being run from a terminal.

     --cdebconf
	   Use cdebconf instead of the traditional Perl debconf implementa‐
	   tion.  In future this may provide enough memory efficiency benefits
	   to be made the default, but for now it is not really worthwhile and
	   is therefore for experimental use only.

     --automatic
	   Skip over questions that have been pre-answered by use of a preseed
	   file.  This is useful for unattended installations.

     --only
	   Tell ubiquity that it is the only desktop program running so that
	   it can customize its user interface to better suit a minimal envi‐
	   ronment.  This allows the installer to be run standalone, reducing
	   memory requirements.

     --query
	   Print the frontend that would be used and then exit.

AUTHORS
     Ubiquity was formerly known as "Espresso", and originally as "Ubuntu
     Express", which is written and maintained by Javier Carranza
     ⟨javier.carranza@interactors.coop⟩ and Juanje Ojeda Croissier
     ⟨juanje@interactors.coop⟩.	 This version draws on the work done on Ubuntu
     Express, but was renamed to avoid confusion, to reduce awkward branding
     considerations, and because Ubiquity concentrates on reusing
     debian-installer code and reducing duplicated translation and branding
     work as much as possible.	Ubiquity has now substantially diverged from
     Ubuntu Express and is an independent project.

     ubiquity was mainly developed by Colin Watson ⟨cjwatson@ubuntu.com⟩ and
     Evan Dandrea ⟨ev@ubuntu.com⟩, with contributions from many others.

     The mythbuntu_ui frontend was developed by Mario Limonciello
     ⟨superm1@ubuntu.com⟩.
