The error in the log is:

This indicates that your package manager configuration is in an invalid state. The libk5crypto3 update was published simultaneously for both amd64 and i386 architectures, and an upgrade should therefore pull both of them in together. You may need to make sure that the mirror your /etc/apt/sources.list doesn't have i386 disabled.
