If you encounter a “Transaction Check Error” on yum on a x64 system during an install, an update or an upgrade, you will find out that most of the time, you can’t remove the problematic packages. But it’s very likely that the problem comes from a i386 version of a package. The easiest way to proceed is just to remove the i386 version of each software or library as it appears on the Transaction Check Error.
PHP 5.2 brings lots of little useful features and CentOS 5.3 comes with PHP 5.1. So most of my PHP apps failed. The easiest way to solve this is to : Edit /etc/yum.repos.d/CentOS-Testing.repo and put this: [c5-testing] name=CentOS-5 Testing baseurl=http://dev.centos.org/centos/5/testing/$basearch/ enabled=1 gpgcheck=1 gpgkey=http://dev.centos.org/centos/RPM-GPG-KEY-CentOS-testing Launch: yum update php Source : Fresh Blurbs
I switched from Debian to CentOS because I had the choice between an old 32 bits Debian 4.0 or a brand new 64 bits CentOS 5.3. And I have some scripts that use the great start-stop-daemon tool, which isn’t available on CentOS. The easiest way to solve this problem is to get dpkg from Debian and then try to compile it. It’s likely that it will fail because libselinux (and it’s subsidiary library libsepol) won’t be registered in the pkgconfig dir.
I’ve switched from my two three years old dedicated servers to one brand new virtual server. Reasons are : These servers costed me too much and they were becoming old (risk of failure increases). It wasn’t worth it. I spent last night doing that because I didn’t want to interrupt anybody using these servers. My two servers were running some Debian and I’m now switching to a CentOS virtual server. I was a little bit worried at first that CentOS would have a crappy package management system, but its yum is in fact working the same way as Debian’s apt-get and OpenSuse’s zypper.
