Php – How to force CentOS yum to use a later version of a package dependency already installed (php-common as a dependency of php-xml)

installationPHPyum

It would appear that the version I have of php-common-5.2.10-1.el5.centos is newer than the one being asked for as a dependency of php-xml when I try to install php-xml using yum install php-xml. The dependent package asked for is php-common = 5.1.6-34.el5_8 as shown by rpm -qa |grep php.

So how would I force php-xml to use the later verion I already have?

(This seems to be the root cause of the problem in related SF question: php-xml install complains of dependency php-common but this is already installed (CentOS) )

Update

output of:

  • yum repolist
  • rpm -qi php-common

(as requested by @ewwhite )is as follows:

Could you provide the output of the following commands?

  • yum repolist
  • rpm -qi php-common

The current version of php-common for your CentOS 5 system is php-common-5.1.6-34.el5_8. Your dependency issue stems from the presence of a newer version of php-common (5.2.10-1.el5.centos) than what is available in the standard CentOS repository. The yum repolist command will help us understand where you're pulling your packages from. The rpm -qi php-common will show us where the currently installed package actually came from.

My guess is that the system was moved to PHP 5.2 using another repo, or maybe by a manual package installation. This has been documented online with the use of the CentOS Testing repository. If your php-common package was a one-off installation, then you should be able to grab the relevant php packages... but this depends on your repolist output...
