CentOS 6.4 cannot read group information from the repository. This is a problem related to your installation tree.

CentOS 6.4 was installed with a USB flash drive yesterday. The following error message is displayed after each partition:
"You cannot read group information from the repository. This is a problem with your installation tree ."

At first, I thought it was a problem with the installation process. After reinstalling the tool many times, the above error is still reported every time.
Later, I found that the CentOS ISO image file in the USB flash disk is not in the correct size, And then I checked the MD5 of the image file in the USB flash disk, which is inconsistent with the official one.
So again from the 163 source to download the CentOS-6.4-x86_64-minimal.iso, download the MD5 verification is correct, and then copy to the U disk root directory.
"The group information cannot be read from the repository. This is a problem with your installation tree ." No longer!

If you want to meet this problem, check whether your ISO image is faulty!
