Hi All, I've just installed a test laptop with CentOS Stream 8.1. I notice that the default install has both CentOS-Base and CentOS-Base-Appstream repos enabled. Is that necessary, or should I just have the Appstream repos enabled. The reason I'm asking is because I'm having trouble updating the installation. The problem seems to be some installed rpms seem to depend on updates from the CentOS-Base repos and others seem to depend on similar updates from the CentOS-Base-Appstream repos and you can't install both. A typical error looks like this. cannot install both qt5-qttools-common-5.12.5-1.el8.0.1.noarch and qt5-qttools-common-5.11.1-9.el8.noarch qt5-qttools-common-5.11.1-9.el8.noarch is from CentOS-Base qt5-qttools-common-5.12.5-1.el8.0.1.noarch is from CentOS-Base-Appstream So updating some installed rpm depends on updating to the Appstream version of qt5-qttools and some other installed rpm depends on the original CentOS-Base version of qt5-qttools. I've played around with --allowerasing --best and --nobest but still can't get a clean update. Thanks, Tony -- Tony Molloy <tony.molloy at ul.ie> Home
