F11 update blockage - missing dependencies

I'm trying to prepare my netbook for a weekend away from home. I expected a big update, but didn't want to install F12 until I get back. The update is stalling, with dependency problems: PyKDE4-4.3 PyKDE4-akonadi-5.4.98-1 PyQt-3.18.1-4 PyQt4-4.7-1 6:kdepim-4.3.98-1 6:kdepim-libs-4.3.98-1 sip-4.10-1 all from kde-unstable, which is enabled. Is this likely to be a simple mirror update not yet complete? If so, I can wait. If it's something else I need to make decisions now.
