I've been using CentOS 6.5 as my OS for quite a while. Usually I don't have many problems with Linux installations, but as they new CentOS 6.6 was released I found myself in a bit of a problem. There were hundred of updates to be done, but only one turned out to be problematic. If I input the commandyum update I getResolving Dependencies--> Running transaction check---> Package scl-utils.i686 0:20120927-8.el6 will be updated---> Package scl-utils.i686 0:20120927-23.el6_6 will be an update---> Package xcb-util.i686 0:0.3.6-1.el6 will be updated--> Processing Dependency: libxcb-icccm.so.1 for package: qt5-qtbase-gui-5.3.2-1.el6.i686--> Processing Dependency: libxcb-image.so.0 for package: qt5-qtbase-gui-5.3.2-1.el6.i686--> Processing Dependency: libxcb-keysyms.so.1 for package: qt5-qtbase-gui-5.3.2-1.el6.i686---> Package xcb-util.i686 0:0.3.6-5.el6 will be an update--> Running transaction check---> Package xcb-util.i686 0:0.3.6-1.el6 will be updated--> Processing Dependency: libxcb-icccm.so.1 for package: qt5-qtbase-gui-5.3.2-1.el6.i686---> Package xcb-util-image.i686 0:0.3.9-4.el6 will be installed---> Package xcb-util-keysyms.i686 0:0.3.9-5.el6 will be installed--> Finished Dependency ResolutionError: Package: qt5-qtbase-gui-5.3.2-1.el6.i686 (@epel)       Requires: libxcb-icccm.so.1       Removing: xcb-util-0.3.6-1.el6.i686 (@anaconda-CentOS-201311271240.i386/6.5)           libxcb-icccm.so.1       Updated By: xcb-util-0.3.6-5.el6.i686 (base)           Not found You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigestNow, I know that often these sort of conflicts come from updates from different repos, but this is my current repo listadobe-linux-i386       Adobe Systems Incorporated base                   CentOS-6 - Base                                    epel                   Extra Packages for Enterprise Linux 6 - i386extras                 CentOS-6 - Extras google-chrome          google-chromespideroak-stable       SpiderOak Stable Distribution              updates                CentOS-6 - UpdatesAnd the weird thing is that it seems that the conflicting packages not only come from the same repository, but are actually dependencies!xcb-util in fact asks me to install xcb-util-image and xcb-util-keysyms as dependencies..and then conflicts with them! The current version of xcb-util does not have these other two dependencies installed, and says that Source RPM: xcb-util-0.3.6-1.el6.sr.This is a bit weird. Has anyone met this problem?Many thanks, and I hope I provided enough information.

Problem is qt5 from epel, I removed it and upgrade without problem. There is already fixed qt5 in epel-testing: https://admin.fedoraproject.org/updates/FEDORA-EPEL-2014-3484/qt5-qtbase-5.3.2-3.el6
