    12.04.1-alt-amd64 fails integrity test

    1. Download ISO
    2. Verify MD5 hash (GOOD)
    3. Copy to USB drive (tried Unetbootin and Live Linux USB Creator, also tried two usb drives)
    4. boot and run Integrity Test
    5. (FAILED) The ./pool/main/x/xserver-xorg-video-ati/xserver-xorg-video-ati_614.99~git20111219.aacbd629-0ubuntu2_amd64.deb file failed the MD5 checksum verification.

    Thoughts? I'm at a loss I've verified the ISO, and the USB drives to be good. It's only the alternative CD I'm having problems with.

    [EDIT] I also tried http://cdimage.ubuntu.com/daily/curr...nate-amd64.iso (Aug 24th). And It fails the integrity check as well:
    xserver-xorg-video-radeon_6.99.99~git20120713.6ef1ad6a-0ubuntu1_amd64.deb

    Thanks,
    Zach

    What happens when you try to install it? Choose the 'nomodset' option, from memory, by hitting F6 at the install screen.

    * If you want to be certain grab the torrent file and get the ISO that way. The MD5sum is checked on the way.

    I get:
    "Installation step failed"
    An installation step failed. You can try to run the failing item again from the menu, or skip it and choose something else. The failing step is: Select and install software

    Syslog:

    Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of incoming.
    The following information may help to resolve the situation:
    The following packages have unmet dependencies:
    xserver-xorg-video-all : Depends: xserver-xorg-video-ati but it is not installable
    Depends: xserver-xorg-video-nouveau but it is not installable
    E: Unable to correct problems, you have held broken packages.

    Are you selecting the software to install? Doesn't look that way. It's asking for things you haven't installed. I've got it right you are using the alternate ISO? It is different to a regular desktop install. May I ask why you're taking this path? To learn more about Ubuntu/Linux?

    Also, again, you may need to set the 'nomodset' option before installing.

    I'm not selecting anything it's just part of the normal installation process.
    Yes I'm using the alt install. The reason is to utilize encrypted LVM.

    I'm not sure how nomodeset will help. It's not until I've setup a usr, partitioned and started installing packages that the installation fails (the graphical installation works fine, which I believe is what nomodeset is used to fix).
    [EDIT] Even though I didn't think it would help I did try 'nomodeset'. Install fails as usual.
    The real problem is the ATI package is failing an integrity check but the ISO is not. Perhaps this ATI package is bad in the repository?

    I'm able to replicate this over and over again so I went ahead and submitted a bug report.
