Error: database disk image is malformed

Yum is a tool available for installing packages on RPM based Linux distributions. I have recently found the following error while trying to install updates on CentOS.  “Error: database disk image is malformed”

 
[root@localhost ~]# yum update
Loaded plugins: fastestmirror, security
Setting up Install Process
Determining fastest mirrors
* base: ftp.usf.edu
* extras: mirror.atlantic.net
* updates: mirror.eboundhost.com
extras | 3.4 kB 00:00 
extras/primary_db | 37 kB 00:00 
updates | 3.4 kB 00:00 
updates/primary_db | 5.2 MB 00:00

This error can be easily fixed by  running following command.

 
yum clean dbcache

That’s it.
