Ubiquity, Failed to execute child process, no such file

[Paul Gorski]

While installing Lubuntu precise-desktop-powerpc.iso 20120309 on an eMac G4 800 MHz, Nvidia graphics, I received an error during the install process:
Failed to execute child process "ubiquity" (No such file or directory)

Steps I took:
1) Boot from desktop .iso, that seemed to work just fine
2) Right click on "Install Lubuntu 12.04" desktop icon, select "Open"
3) Installer window is black/dark
4) So I open Customize Look and Feel, change widget to Clearlooks and background color (customized color them) to a nice purple
5) Installer text visible now, so I choose Install
6) I choose "update this installer" and Install
7) I had enough drive space and internet connection
8) I choose dowload updates and download extras
9) choose Install
10) wanted to go back and turn off download updates, but when I choose the "Back" button, the system seemed to freeze, then I received the " Failed to execute child process "ubiquity" (No such file or directory)" error.

To file this report, I used "apport-bug lubuntu-desktop" from LTerminal, so the computer seemed to be working fine from the live CD.

20120310 worked on the eMac G4, but I received this error:

Ubiquity, Failed to execute child process, no such file
when trying to launch the installer for 20120310 on an iBook G4 800 MHz, 768 MB RAM

(Same problem, different date, different computer)

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running only once:
apport-collect <bug #>

and any other logs that are relevant for this particular issue.

I've marked this as invalid - as PPC is no longer supported by Lubuntu
