Ubiquity crashes with "Illegal instruction" right after starting the slideshow

It's my only system that's a first generation AMD Athlon 1Ghz.

Status changed to 'Confirmed' because the bug affects multiple users.

Just before crash (on istaller log):
"Error opening file for reading: Permission denied"
After crash:
"The installer encountered an unrecoverable error. (Somethong like this)) You will now enter a live session to investigate the problem. (Drops into live session).

These should not be taken as direct quotes, as I only quicky wrote these messages down.

My specs:
AMD Sempron 32-bit (2004?)

Yeah, the Permission denied error isn't relevant to that bug, what's is the Illegal Instruction error, though you can't see it as it doesn't show up in any of the logs (yeah, that's a bit annoying :)).

If you try running "sudo /usr/lib/ubiquity/bin/ubiquity" from a live session, I think you'll see "Illegal Instruction" show up in the terminal right when the slideshow starts (or switches to the first slide, can't remember).

Hello ,

The crash occurs when a plein installation runs, right after reaching the slideshow.
"The installer encountered an unrecoverable error. A desktop session will now be
run so that you may investigate the problem or try installing again."

This bug affects computers with AMD processors : Athlon, Athlon XP, Duron, Sempron for all 12.04 distributions (not for 11.10).
It seems that it occurs with VIA KT133/400/600 chipsets (but not only).

Systems where the bug were oberved :
  - MSI MS-6340 | VIA KT133 | Athlon XP (1.4 GHz)
  - Gigabyte GA-7 VA SMFS | VIA KT400A | Sempron 3000+ (2GHz)
  - Asrock K7 upgrade 600 | VIA KT600 | Barton 2800+
  - ASUS A7V8 | VIA KT400 | Duron 1800+
  - Asrock K7S41 | SiS 741 | ?
  - Asus A7N8X-X | NVidia nForce2 400 | Athlon XP 3000+
  - MSI KT4VL | VIA KT400 | Athlon XP 2000+ (1.86MHz)
  - Laptop Sony Vaio VGN-FE11M | Intel PM945 | Intel Core Duo T2300 (1.66 GHz)

Cool, thanks for the list, would it be possible for you to get the content of /proc/cpuinfo for all of these?

The first two are in the computer class-room of my primary school. I'll see that to-morrow.
For the others (french, english languages), I contact them through their forums.

Same problem with Barton 3000+

Ubiquity crash just after typing username, hostname, etc,

I have a similar problem on my PC (AMD Duron 1800, 1,5 GB RAM, BIOS from 2003).
Maybe it's the same cause, maybe not, I don't know. Can you help me find out?
(BTW: this CPU _does_ support PAE, as I checked!)

The effect started after the last "Oneiric" / 11.10 kernel upgrade, just a few weeks before "Precise" / 12.04 came out, approx. around March 2012.

Since I made this kernel upgrade certain things did stop working:

1) All auto-replace functionality in LibreOffice stopped at once,

2) The presentation of any (!) streaming video content is no longer possible,
both in Firefox and Chromium. Instead the video only an empty rectangle appears,
no Flash message. Despite this it is still possible to download youtube movies with the respective Add-On, but not to watch on screen. (I tried both Flash and Gnash, no change).

3) Wine doesn't start any more.

4) Google Earth doesn't start any more

5) Stellarium doesn't work

Or, maybe, it is my graphics card that will not work with the new kernel:
It's a Sapphire Radeon 9000 Pro from ATI.

Can all these things have a common cause?
Who can give me a hint how to find out?

Thanks,

-ah-

Hi everyone,

It seems that Ubiquity still doesn't work on 32 bits AMD platforms... I try to install Ubuntustudio 12.10 and since the "killing" of the alternate CDs, I MUST use Ubiquity.

And during the slideshow, after the first slide Ubiquity crashes just changing to the second slide, also when I manually change to the second slide.

I also tried to start with the nomodeset option, with the vga=791 option and some others, with no better results.

I followed the page "https://wiki.ubuntu.com/DebuggingUbiquity" and I did start Ubiquity by the command line with "ubiquity -d" and il finally fails with the "Illegal instruction" error.

My platform is:
- CPU: AMD Athlon XP 2400+ (Thoroughbred series), 2 GHz
- Chipset: nForce2 IGP + MCP (IGP desactivated)
- RAM: 2 GB DDR2
- Graphics: ATI Radeon HD 3450 AGP
- HDD: 80 GB PATA, 3 partitions (15 GB for "/", 3 GB for Swap, 60 GB for /home)

Ubiquity version: 2.12.16
Ubuntustudio version: ubuntustudio-12.10-dvd-i386.iso (32 bits)

If you need more infos, ask me and I will post more...

A little news about this bug:
In the live-CD session, I manually removed "ubiquity-slideshow-ubuntustudio" package (via Synaptic) and Ubiquity did its job.

So it seems that the Ubiquity Slideshow doesn't run and makes Ubiquity to crash.

Regards,
Johan

I can verify that Johan's workaround works. By uninstalling ubiquity-slideshow-ubuntustudio I was able to install 12.10 32bits on Sempron 2800+ with 768 MB Ram.
