It appears this bug occurs when there is a "PreDepends" that conflicts with another "Breaks" rule.
Here's some output from my attempt to repair it, which may be helpful for you: woodpecker:/var/cache/apt/archives# dpkg -i sysvinit_2.88dsf-45_amd64.deb systemd-sysv_204-6_amd64.deb dpkg: regarding sysvinit_2.88dsf-45_amd64.deb containing sysvinit, pre-dependency problem: sysvinit pre-depends on sysvinit-core | upstart | systemd-sysv sysvinit-core is not installed. upstart is not installed. systemd-sysv is not installed. dpkg: error processing archive sysvinit_2.88dsf-45_amd64.deb (--install): pre-dependency problem - not installing sysvinit dpkg: regarding systemd-sysv_204-6_amd64.deb containing systemd-sysv: systemd-sysv conflicts with sysvinit (<< 2.88dsf-44~) sysvinit (version 2.88dsf-43) is present and installed. dpkg: error processing archive systemd-sysv_204-6_amd64.deb (--install): conflicting packages - not installing systemd-sysv Errors were encountered while processing: sysvinit_2.88dsf-45_amd64.deb systemd-sysv_204-6_amd64.deb I have worked around the bug by doing "apt-get install -t sid sysvinit-core" after which I was able to upgrade systemd. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
