    [SOLVED] Hangs at 15% during Install process

    I'm trying to install Mythbuntu 7.10 on a VIA M10000 via a DVD drive.

    Problem is, it keeps hanging at 15% during the installation, as it hits the "Detecting drives" stage!

    I've left it for up to an hour and it didn't move a bit. Also tried using the guided partitioner and also the manual one. Memory and HDD checked, neither have any errors. Tried partitioning and formatting the HDD in the terminal before install, but of course the installer insists on reformatting it... which I think might be the problem.

    System goes very slow on the run up to 15%, so it's hard to switch to a console and get any debug output, unfortunately

    Any ideas?

    Not sure how that would help. I've already verified my ISO is correct using the md5sum. In addition, I've tried installing both off a burnt DVD, and also from a usb stick, and had the same problem each time.

    So I don't think it's the source media.

    Ok, well I'm going to leave it running until lunchtime. Right now it's sat at 15%, accessing the DVD drive every 4 or 5 seconds. Over and over again!

    Looks like it's running out of memory:

    ...although, thinking about it, if there's a process that keeps sucking up memory, even if I upgrade to 4GB, it'll still fail

    You may consider adding your logs from /var/log/installer on the resultant system to this bug:

    Re: Hangs at 15% during Install process

    Think that might be a slightly different issue. My installer logs don't give any indication of failure or error at all beyond normal debugging output. Only the kernel output shows any problems.

    I've got more memory on the way, so if that fixes the problem, hopefully we'll know that was the issue.

    If that doesn't work, I'll pop this into launchpad as advised.

    Re: Hangs at 15% during Install process

    Well I popped in 512MB today, and it worked like a charm first time. Stopped only at 15% for about 10 seconds, and then started formatting the drive.

    Exact same settings as had failed upteen times during the weekend.

    So anyone else having this problem - make sure you have at least 512MB of RAM!
