Some errors that came up during a Red Hat Enterprise Linux install:

 

Unable to read package metadata. This may be due

to a missing repodata directory. Please ensure that

your install tree has been correctly generated.

Cannot retrieve repository metadata (repomd.xml)

for repository:  anaconda-base-201003220802.x86_64.

Please verify its path and try again

 

So I ran the Red Hat Enterprise Linux Media Check and received the result below.

What you don’t want to see:

—————–| Media Check Result |—————–

The media check FAILED for the image:

Red Hat Enterprise Linux Server 5.5 DVD

The image which was just tested has errors. This could

be due to a corrupt download or a bad disc. If

applicable, please clean the disc and try again. If

this test continues to fail you should not continue

the install.

I cleaned the disk and ran the Media Check again—Still failed.

Sometimes just cleaning the disc resolves the problem. Sometimes it’s because the DVD drive on the system you are installing on won’t read some discs correctly that were burned on other DVD drives.

Or your media could just be suffering from bit rot.

What you want to see:

—————–| Media Check Result |—————–

The media check PASSED for the image:

Red Hat Enterprise Linux Server 5.5 DVD

It is OK to install from this media.

If you are still getting errors on your burned iso image for your Red Hat linux install, you may need to re-download the image and burn it again to a fresh DVD.
