I've not seen that behavior in a long time. I will watch, from time to time, the output in /var/cache/akmods/akmods.log while doing a "dnf update". These lines 2017/08/28 14:30:20 akmods: Checking kmods exist for 4.12.9-300.fc26.x86_64 2017/08/28 14:30:21 akmods: Building and installing nvidia-kmod don't appear until the last "clean up" line appears in the update process. Then I would see... 2017/08/28 14:31:12 akmods: Installing newly built rpms 2017/08/28 14:31:12 akmods: DNF detected And not until the last "verify" is finished will I see.... 2017/08/28 14:32:03 akmods: Successful. And you'll notice the time difference. -- Fedora Users List - The place to go to speculate endlessly
