I thought I had a pretty good grip on how yum works, but it seems I'm wrong. I'm trying to do an update, and I'd like to exclude some packages that are giving me dependency problems. Specifically I'm trying to update from FC3 to FC4. I've tried doing this: yum --exclude=koffice --exclude=pythonabi --exclude=apt --exclude=kdenetwork --exclude=libmal --exclude=kdegraphics --exclude=kdeaddons --exclude=kdepim --exclude=gcc-g77 --exclude=kdeedu --exclude=libgcrypt-devel --exclude=python-reportlab update on the command line but I still get errors about missing dependencies. So I added this to my yum.conf: exclude=koffice pythonabi apt kdenetwork libmal kdegraphics kdeaddons kdepim gcc-g77 kdeedu libgcrypt-devel python-reportlab which yields the same results when I run "yum update" Reading the man page for yum, and other online documentation it looks like I'm doing both of those correctly, but I'm obviously missing something. I've got yum 2.2.1 and FC3. Any advice would be appreciated. Thanks, Rob
