Can you confirm that the system was disconnected from the network (it looks like there's no wired network and wireless was not configured) ?

[Colin Ian King (colin-king)]

Just to confirm, the laptop was not connected to the network (no ethernet connection and the wireless was not yet associated with my Access Point)

[Jean-Baptiste Lallement (jibel)]

It is reproducible when running an OEM install without network connection.

Thanks.

This bug was fixed in the package ubiquity - 2.7.11

---------------
ubiquity (2.7.11) oneiric; urgency=low

  [ Luke Yelavich ]
  * Use at-spi2 dbus launcher to start the at-spi2 daemon
  * Determine accessibility state from gsettings using the gsettings command,
    to make sure privileges are dropped

  [ Colin Watson ]
  * Handle the case where one of the packages returned by 'pyversions -s' or
    'py3versions -s' is not installed (LP: #806349).
  * Add --config=Mode:0644 to debconf-copydb call, as otherwise we leave
    /var/cache/debconf/config.dat mode 0600 in the installed system,
    breaking the first run of some package management frontends
    (LP: #442941).
  * Provide build-arch and build-indep debian/rules targets.
  * Automatic update of included source packages: console-setup
    1.57ubuntu21, flash-kernel 2.28ubuntu26.
