Hi, I once installed the unofficial mesa-10.1 update provided by fschwarz - which also installed a newer version of libxcb. Since then, Fedora-20 includes mesa-10.3 and most packages provided by fschwarz have been replaced by newer versions contained in the official fedora repo. However, I still have a newer version of libxcb installed (1.10.1) whereas fedora only provides 1.9.1. Recently I tried installing QT5 and it failed: Error: Package: qt5-qtbase-gui-5.4.0-2.fc20.x86_64 (updates) Requires: libxcb-xkb.so.0()(64bit) Available: libxcb-1.9.1-3.fc20.x86_64 (fedora) libxcb-xkb.so.0()(64bit) Installed: libxcb-1.10-1.fc20.i686 (@fschwarz-mesa10-i686) Not found Error: Package: qt5-qtbase-gui-5.4.0-2.fc20.x86_64 (updates) Requires: libxcb-sync.so.0()(64bit) Available: libxcb-1.9.1-3.fc20.x86_64 (fedora) libxcb-sync.so.0()(64bit) Installed: libxcb-1.10-1.fc20.i686 (@fschwarz-mesa10-i686) Not found Any attempts to replace libxcb-1.10 with the officially provided libxcb-1.9.1 failed. "yum reinstall" complains libxcb-1.10 is no longer available, and yum remove would pull all dependencies along with libxcb (3.9G) which also isn't such a great idea. So any idea how to get rid of libxcb-1.10.1 are very welcome ;) Thank you in advance, Clemens -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
