How To Fix “Error: database disk image is malformed” On CentOS / Fedora

Today I have been trying to update my CentOS 6.5 virtual machine using command “yum update”.

# yum update

Sample output:

Error: database disk image is malformed

I got a weird error “Error: database disk image is malformed” and my system didn’t get updated.

How do I solve this error?

To get rid of this above error, enter the following command From Terminal:

# yum clean dbcache
