[Bug 473389] Re: checksums does not match.

[Jian Wen]

Make sure the sha1sum of iso is OK by searching the value on Google

When it fails with "checksum does not match", do the following steps

Find out which one failed
cd $usbdrive_path
md5sum -c md5sum.txt 

Copy the mismatched file to you hard disk, check the checksum again.
If the checksum does not match, too.
Check the filesystem.
umount $usbdrive_path
sudo fsck.vfat -nVv /dev/sdb1 #adjust the path

Repair it
sudo fsck.vfat -a /dev/sdb1
I am not sure if the above command is the best command to repair the fs.

Title:
  checksums does not match.

Status in “usb-creator” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: usb-creator

  1) $ lsb_release -rd
  Description:	Ubuntu 9.10
  Release:	9.10

  2) $ apt-cache policy usb-creator-gtk 
  usb-creator-gtk:
    Installed: 0.2.12
    Candidate: 0.2.12
    Version table:
   *** 0.2.12 0
          100 /var/lib/dpkg/status

  3) I expected to create a boot disk.

  4) I received a message saying that checksum does not match.

  I try to create the boot disk from Ubuntu 9.10 RC, using an iso from
  Ubuntu 9.10 Final. I verified the md5sum of iso image and it's correct
  but every time I try to create the disk I got this message. So I
  burned a CD and installed 9.10 Final. Then I try to create boot disk
  again, but the same error happened. (I'm using amd64 version but tried
  to create a boot disk with i386 image and amd64 image, both have the
  same problems)

  Is there any other information, that can I post here?
