Description of problem: when running dnf update it shows: Total download size: 315M but yum says for the same transaction: Total size: 315 M Total download size: 177 M which leads me to conclusion that dnf confuses install and download size Version-Release number of selected component (if applicable): dnf-0.3.9-1.giteff4c49.fc19.noarch How reproducible: 100% Steps to Reproduce: 1. run dnf check-update 2. run yum check-update 3. compare the reported download size
Ah, this is not actually a bug. Both DNF and Yum report "Total size" for the total size of the .rpm files about to be installed, and "Download size" for the total size of the .rpm files aobut to be downloaded. What you are seeing is that Yum has (315-177) MB of rpms in its cache already so doesn't have to download them, but DNF doesn't share Yum's cache and in this case it can not see the files in its own cache so it correctly reports them all as to be downloaded yet. Closing as NOTABUG.
