Have used Ubuntu for years now. Bought a Samsung 305v5a-so2 laptop yesterday. It runs an AMD A8 quadcore. I have a CD of 10.04 and as I am not clear about whether to install 32 or 64 bit I thought I would run the trial of ubuntu from the cd to see it.

After about 30m started getting Authentification Failure messages.

Squashfs-error Unable to read fragment cash entry

Then a zillion Buffer Logical error messages like 17,000+

Should I go download 11.10, in 32bit or go and try the 64bit.

Really don't want to screw the new laptop already but aint gonna wanna work with w7 either.

Thanks for any help

That is an error with the LiveCD/USB filesystem, it might be corrupted so re-Download the ISO and once you get it to install update the kernel because the CPU is brand new Llano CPUs are new and the newest kernel should be better for these CPUs. – Uri Herrera Dec 17 '11 at 17:04

  1. Download Ubuntu 11.10 from here. 32bit or 64 bit, either will work fine on your laptop.
  2. Follow the directions at the link to make a bootable CD or USB stick. Click the 'Show me how' button to see that you are doing the steps correctly.
  3. Install Ubuntu following the guide on the same page as above.
  4. If you still have errors after following the guide exactly, post the error messages up here with any specifics. Try to copy any error messages you see word-for-word. This helps us both.

Tom Thanks for that. This was going to be my next step tomorrow I was also going to boot from the cd and install into a separate partition to bypass w7. I am still not sure, would you recommend 32bit or 64 in the end seems to be a lot of conflicting stuff. Thanks – Antony Dec 17 '11 at 14:03
If you have >4GB RAM, 64 bit can use it more efficiently. 32 bit is compatible with more applications, especially older ones. Don't spend much time worrying about it. If you ask ten people which they prefer you will get ten different answers. All would be correct. The suggested default now is 32 bit, so use that. – Tom Brossman Dec 17 '11 at 14:23
Regardless of the Memory amount 32 bit can take more than 4GB it's a myth now, and specially for linux it's a non existant limitation that lives in peoples mind. 64bit is compatible for %99 of the software these days and works fine with older software and hardware. Seeing his is an A8 quad-core processor perfectly capable of using 64 bit instructions there's no need for him to keep using Legacy old 32 bit Ubuntu. – Uri Herrera Dec 17 '11 at 17:00
@UriHerrera I wouldn't say non-existant limitation, 32bit still has a maximum of 2GB addressable by any one process which can really suck if you want to run a big database or something. PAE does work around some of the issues but not all. Anyway I agree that 64bit is the present and the future so go with that. – Caesium Dec 17 '11 at 17:04
One can increase the addresable memory one process can take, right?. – Uri Herrera Dec 17 '11 at 17:05

Squashfs is the filesystem which resides on your live CD. As the CD is probably somewhat old, there may some scratches or other damages on it. This leads in most cases to the Squashfs errors. So it is a safe choice for you to download the latest Ubuntu CD or DVD and use it like Tom suggested.
