I have the same issue when ubiquity start installation (at 2%) doing partitions

[mmbossoni (mmbossoni-gmail)]

Workaround to install is to uninstall ubiquity slideshow
sudo apttitude purge ubiquity-slideshow-ubuntu ubiquity-slideshow
The installer works in the same way as in 9.04

[Martin G Miller (mgmiller)]

Attempting to install from desktop CD also gives this problem. The install window fails and drops you back to the live CD desktop. It also does this if you choose to install the system from the live CD without running the live desktop. It fails out the process and puts you onto the live CD desktop.

The command you give above: sudo apttitude purge ubiquity-slideshow-ubuntu ubiquity-slideshow returns error messages.

I went into synaptic and "completely" uninstalled ubiquity-slideshow-ubuntu.

It now seems to have installed normally and is ready to be restarted on the hard drive for the first time.

Amazing that you can do all this from the live session while it's installing.

So I installed the beta on several machines. This bug affects 2 to 5 machines. It is a problem ...

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate an useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system

encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

@Martin and mmbossoni:
Martin, if you copied and pasted the purge command, that might have been the reason the workaround didn't work for you. mmbossoni typo'd an extra "t" in "aptitude." I tried the workaround, and so far, so good.

[Alexander Sack (asac)]

is this reproducible? Maybe we can get a better backtrace?

[mmbossoni (mmbossoni-gmail)]

Hi
I can reproduce the bug 100% of the time in my machine.
Maybe the libwebkit was compiled with an incompatible instruction set for my processor (An Athlon XP 1600+).
Access non existent instructions can cause sigill (we cannot use SSE2 instructions in a processor without them for example, but the processor that compiles the code can have it).
On my Vostro1000 laptop with a Turion64 X2 TL-60 everything works.

[Cedric F. (c-fachinetti)]

Ok, I have an athlon XP 2500+, and I have the same problem !

[madbiologist (me-again)]

I'm also getting this when attempting to install from the desktop liveCD of Karmic 9.10 beta.

Uname: Linux 2.6.31-11-generic i686

I'm not sure if it is a cross-compilation problem, but just in case, I have an AthlonXP 2700+

Of course the way to test this would be to get the source code for libwebkit and compile it on an affected system, but I can't do this at the moment, if at all (have never compiled anything before).

[Colin Watson (cjwatson)]

We don't use any compiler flags to set the architecture to anything other than the default when building webkit, but webkit does include inline assembly which is a classic cause of this kind of thing. Unfortunately the automatic retracer doesn't seem to have done anything useful with the stack trace, so it's a bit hard to pin down ...

[Sebastien Bacher (seb128)]

could be similar to bug #452574?

[Cedric F. (c-fachinetti)]

In the last daily-build of 20, this bug seems to have disappeared...
Can anyone confirm ?

[Julio Danni (jdanni)]

This seems fixes in Releasae Candidate

[madbiologist (me-again)]

I am no longer getting this with the desktop liveCD of Karmic 9.10 Release Candidate.

Uname: Linux 2.6.31-14-generic i686

The install no longer fails with an error near the end of the install process, followed by returning me to the liveCD desktop. The install now completes successfully and prompts for a restart of the system.

I am also seeing the install slideshow for the first time - it did not appear during the attempt to install from the beta liveCD (and appears to have been the cause of the problem - purging it from the beta as suggested above worked for me too).
