[senthil_kumar_1]

Hi All,

I have tried to install

# yum install php-mysql
Loaded plugins: rhnplugin, security
Setting up Install Process

You could try using --skip-broken to work around the problem
You could try running: package-cleanup --problems
package-cleanup --dupes
rpm -Va --nofiles --nodigest
The program package-cleanup is found in the yum-utils package.



PS: Take a look at last line.


My Questions:

1)what is the purpose of "Package-cleanup"?

2)How to install and use "Package-cleanup"?

Shalom,

Package cleanup is used to clean up redundant or superseded packages. It can also clean up the wreckage from failed updates/installs.

yum -y install yum-utils

It is in my mind a must have.
