Then tried to launch trough terminal it writes already running. So I assume that something wrong with graphical part.

[DonnieD (donnied)]

when tried sudo ubiquity I get : "Bus error (core dumped)"

Managed to install after reformating usb and making new usb install. But still ubiquity launched not very easy.
Installer debug and syslog attached

I got it to work after after installing 'gksu' and installing it through 'gksu ubiquity'.

[Dimitri John Ledkov (xnox)]

One should use:
$ pkexec ubiquity

gksu is deprecated and to be removed from the archive soon.

Does it work when launched with pkexec?
