Re: [CentOS] php-pear problem on yum update
Hello Nikos, On Fri, 2012-03-09 at 11:16 +0200, Nikos Gatsis - Qbit wrote: I have never Install a package out of yum so this conflict is very strange to me. I try to clean up yum, and update with --skip-broken with no luck. The .rf packages come from the Repoforge (formerly RPMForge) repo. The conflict you see is caused by similar packages being provided by multiple repos. You can only fix that by excluding them from all but one repo. Is good to install php packages excluding php-pear? Actually I dont use it. The fact that you have so many PEAR packages on your system suggest someone on your system might be using them. Don't blow them away unless you want to break existing PHP websites that use them. All that said, for me the easiest approach managing PEAR packages is just using PEAR itself to install and update modules. Install the php-pear rpm once, then exclude it from the updates in your base repo config. (If you take this approach yourself make a list of the installed pear module rpms before you uninstall them with yum. After uninstalling the rpms you have to reinstall the modules using pear install.)
