It’s a little over a month since Fedora 20 was released, but during a terrible bout of insomnia last night I decided to upgrade my desktop PC.
The upgrades using “fedup” worked fine for the previous releases (Fedora 18, Fedora 19). Unfortunately, it failed abysmally for the upgrade to Fedora 20. I tried a few times, but I was not able to troubleshoot it, so I gave up and did a reinstall.
I’ve got an SSD for the system drive, but keep almost everything of importance on a second drive (and a backup drive). I tend to do most things in VMs, so I ended up doing the following:

My internet provider said my service was degraded due to the large amount of data uploading from my computer. As far as I knew, my computer wasn’t uploading anything but I didn’t know how to prove it.
