I successfully updated my operating system to Fedora 20, which bears the name "Heisenbug". I had failed on the release date Tuesday because the automatic update tool was outdated, and because my system would not retrieve a security (GPG) key for a software center called RPMFusion-non-free. Tuesday I solved the first problem, and last night either I or the Fedora updates solved the second problem. It turned out to be simply finding the command to download a key, after the system failed to do so. I fell asleep in my chair while the update was in session, and awoke to see its completion.
In other news, I now think of Scott Pilgrim v. the World as a classic holiday movie. Like White Christmas, It's a Wonderful Life, and Miracle on 34th Street, I watch it over and over. I think it's more, too, than a crush on Mary Elizabeth Winstead's version of the character Ramona Flowers. It's more like finding oneself in a world of confusing meaningless confrontations.
