ubiquity

is a graphical installer for Ubuntu, written largely in Python, using c debian-installer as a backend for many of its functions. It is normally invoked from a desktop icon, and presents a "wizard"-style graphical user interface. must be run as root, and will escalate privileges for itself using c gksudo , c kdesu , or c sudo as appropriate.

pdb Drop into the Python debugger in the event of a crash. Only effective if is being run from a terminal.

cdebconf Use c cdebconf instead of the traditional Perl c debconf implementation. 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.

no-migration-assistant Disable c migration-assistant , which attempts to migrate documents and settings from other installed operating systems. If the migration process causes problems, please file a bug and use this option.

Ubiquity was formerly known as "Espresso", and originally as "Ubuntu Express", which is written and maintained by and 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 c 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.
