WUBI 10.04 and 12.04 stops after the pre-copy

[Daggi Duck]

WUBI for Ubuntu-Desktop 10.04 and 12.04 Beta1 stops after the pre-copy phase. WUBI for Ubuntu-Desktop 8.04 works without the problem on the same PC.

Can you try with http://people.canonical.com/~evand/wubi/precise/wubi-r263.exe instead?

It's likely a bad burn on the CD - based on historical reporting of errno
22. Try booting your computer from that CD and run the CD check from the
extended menu (hit space when you see the keyboard/man icon). That should
confirm it.

You can either run wubi.exe standalone (as suggested) or with the
downloaded ISO in the same directory - but whichever way make sure the bad
cd is not in the drive or wubi will find it and fail again.

Many thank's for your prompt support.

I have tried the installation with the new downloaded version of WUBI. With the burned CD it gives the same error (see the attached log file). But the new version of WUBI do not complains the empty cardreader drive G: as the old version do it some times.

Then I have booted with the CD and the live system ist running without any error. Next I have booted with the CD and choose checking the CD from the extended menu. The CD check gives no error!

Last I installed the Ubuntu-Desktop without the CD, but with the nev version of WUBI and the downloaded ISO file (which was burned at the CD) at the same directory without any error (see the attached log file).

This way, my problem is solved, but not the problem to install with the burned CD. If you need more tests to solve fully the problem with the WUBI installation with a burned CD, I will do that for you.

So not a bad burn... bug 207137 mentions a case where the optical drive can be a factor in the failure - the install was successful when the CD was in the DVDROM drive, but not the CD/RW drive on the same computer.

So it points more to something in the code src/wubi/backends/common/utils.py:
def copy_file(source, target, associated_task=None):
    '''
    Copy file with progress report
    '''
    if os.path.isfile(source):
        file_size = os.path.getsize(source)
    elif os.path.ismount(source):
        if sys.platform.startswith("win"):
            file_size = get_drive_space(source)
            source = "\\\\.\\%s" % source[:2]
    if associated_task:
        associated_task.size = file_size/1024**2
        associated_task.unit = "MB"
    source_file = open(source, "rb")
    target_file = open(target, "wb")
    data_read = 0
    while True:
        data = source_file.read(1024**2) <===== line 202
        data_read += 1
        if data == "":
            break
        if associated_task:
            if associated_task.set_progress(data_read):
                source_file.close()
                target_file.close()
                return
        target_file.write(data)
        if data_read >= file_size:
            break
    source_file.close()
    target_file.close()
    if associated_task:
        associated_task.finish()
