The problematic dependency chain is this: libgtk-3-0 -> libgtk-3-common -> dconf-gsettings-backend -> dconf-service -> default-dbus-session-bus | dbus-session-bus dbus-x11 Provides: dbus-session-bus, but apt prefers to replace sysvinit-core with systemd rather than just install dbus-x11. One way to reproduce this problem, in buster or sid: 1) clean chroot 2) apt-get install sysvinit-core 3) apt-get install emacs If you install dbus-x11 right before attempting to install Emacs, apt will not attempt the init system replacement. -- Sean Whitton signature.asc Description: PGP signature
Bug#940965: apt: Fails to find a solution for libgtk-3-0 and sysvinit-core
Package: apt Version: 1.8.2 Severity: normal -BEGIN PGP SIGNED MESSAGE- Hash: SHA512 Hi, apt's resolver does not find a working solution for installing both libgtk-3-0 and sysvinit-core, or for installing libgtk-3-0 when systemd-sysv has a negative score in preferences. Aptitude resolves both of these by favouring dbus-x11 over dbus-user-session. When presented manually with this solution, apt accepts it as valid.
