when 'Error: Nothing to do' error occur in install through yum?
 

I know one situation of this will occur when u already installed the latest version of a package then it will occur. is there any other situations that this error occur?

Fixed the Error.

Case is when the package is excluded. For example my system's yum.conf file contains

exclude=*.i386 *.i586 *.i686

This means any i686 package is excluded by default! A workaround for that case is:

sudo yum install --disableexcludes=all foobar.i686.rpm
