Bugs against SKYPE should be reported against their bugbase.

Ubuntu can't do anything about this, as it is proprietrary third-party-software.

Reading from the logs that the installation language is german I would highly recommend for you to seek help at the german ubuntuusers-forum [1].

Beforehand I can let you have the link to their Community-Wiki regards to Skype [2]

The error seems to be caused by the last installation candidate (skype-bin), i386-package on 64-Bit installation.

[Steve Langasek (vorlon)]

This shows an upgrade failure in the libqtcore4 package, not in skype.

Status changed to 'Confirmed' because the bug affects multiple users.
