Bug Description

I'm installing Ubuntu 10.04 using Wubi on Windows XP sp 3, Wubi finishes and asks if I want to reboot, I reboot and select Ubuntu. The installer seems to progress, however later the following pop-up appears

"The installer encountered an unrecoverable error and will now reboot".

So I have no other option than restarting the PC and that leads to the same error all over again.

========
Important:
========

1. Wubi 9.10 (i.e, the previous version) works flawlessly. So there is definitely no problem with either the Windows installation or the HDD.

2. I tried Ubuntu 10.04 using the live cd mode as well as using Sun VirtualBox (virtual machine) and found no problems - Ubuntu is working fine. So, there is definitely no problem with the downloaded cd image of Ubuntu 10.04.

======
Update
======
I recently discovered that there is absolutely same problem with Kubuntu 10.04 as well.

I encountered the same "The installer encountered an unrecoverable error and will now reboot." on a Dell Latitude CPx. Any way we can help to troubleshoot? I really don't want to install Ubuntu 10.04 on a separate partition.

The only mode that'd allow me to get to Ubuntu is the "Demo mode" (last one in the list after you hit "Esc"ape after choosing "Ubuntu" from the boot loader).

I tried the "Safe graphic mode" and "Verbose mode" and those attempts ended up with the same error message. I also tried "ACPI workarounds" and that'd hang at some point.

This looks like an error with the installer itself and not with Ubuntu.

Yeah, I tried with another laptop (HP Compaq NC6000) and ended up with the same fate. Anything we can help to diagnose? I'm new with Wubi. How quickly are serious issues like these fixed?

Same on a Dell Inspiron 1420 using Oracle Virtualbox 3.2.0 on Ubuntu 10.04. Host is a 10.04 (64bit), Guest is a 10.04(32bit).
The full error message is "The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again". Tried to reinstall several times.

Just in case this is able to help someone in some way...

I had this trouble to using 10.04 and VirtualBox 3.2.0 but I eventually got it to work. (Note that using the CD in "Live" mode always works, it's the installation that fails.)

I created a new VM using most of the defaults except that I created a fixed size disk image and I set the network adapter to "bridged".

I tried the standard install and was given at the end of the install the message as described in the bug report above.

I tried the suggestion as given in the "known bugs" by Canonical:

 ...restart your computer with the CD inserted, press any key at the splash screen, and select “Try Ubuntu without installing”. Once the desktop appears, use the “Install Ubuntu 10.04″ icon to begin installing Ubuntu."

This didn't work.

I went into the VM Settings and made several changes:

 - Under "System" --> "Motherboard" I:
 - - changed "Enable IO APIC" from unchecked to checked,
 - - changed "Enable absolute pointing device" from checked to unchecked,
 - Under "Display" --> "Video" I changed "Video Memory" to read "32MB",
 - Under "Storage" I removed the SATA controller and attached the disk image as a Primary Master on the given IDE controller.

I then reinstalled 10.04 in the usual way, erasing the hard disk image, and it completed without issue.

Since I made several changes at once I can't be sure which was the necessary change, but I suspect that it was "Enable IO APIC".

Since this is a Wubi related discussion can we please keep Virtual Machine / Live CD / EXT 3 Installation related discussions to a minimum ? I dont know why the ubuntu developers are not at all bothered about this Wubi issue. Is there any way we can highlight this problem to them ?

I am facing the same issue as well with 10.04. Should i otherwise start using a lower version like 9.10 and how difficult it would be to upgrade to 10.04?

How is this invalid?

I've encountered this with 10.04 today both letting Wubi download the .iso and using a known good Live CD.

Both the live session and a true hard drive installation of 10.04 work fine on this hardware, I just need to test some grub2 updates for regression in Wubi 10.04, but it's not possible due to this bug.
