You appear to have a system that had all i386 packages, but then you recently tried to install all amd64 packages, is that correct? Your dpkg log shows the final entry trying to install systemd:amd64, which then removes systemd:i386.

Yes. Although the truth is that I have already managed to install the 64-bit version of systemd.
