Comment 2 for bug 634697

Hi Marc! Thanks for your bug report. The bug you describe has been fixed in the branch I have linked and should be available in the next release. Please continue to report any bugs you may find in software-center. Thanks again for your help!

For the aptdaemon error, it seems that you may have closed your browser (this erases the tmp files and hence the deb files) before you clicked install in s-c?
