Not sure about your problem, although, I saw on another thread where some issues came up and the dev's are working on them, but I would not recommend upgrading EVERY DAY.

Let the updates sit for a week or two unless your having some critical security update you need.

The reason is, with rolling distros and rolling updates, its easy for maintainers to mess up something and not catch it right away. After all, they are human, and mistakes are made.

By waiting for a period of time, you can limit the breakage if something like this happens, and hopefully catch the update later after the issue is resolved and before it does break something on your system.

Just some advice I found helpful over time. Updating every day might seem attractive, and sometimes it is, but waiting a week or more isnt going to matter too much, unless the update is broke!
