Public bug reported: basic.target waits for dbus.socket (via sockets.target) AND dbus.socket waits for basic.target, too, delaying dbus-daemon startup. At some point a timeout happens, dbus is started and all queued services try to start registering to the bus at the same time.
All services registering at the same time, seems to be triggering bugs like this more often: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/1871538/ This happens since Hirsute (dbus 1.12.20-1ubuntu3), where the following delta was added: Index: dbus-1.12.20/bus/dbus.socket.in =================================================================== --- dbus-1.12.20.orig/bus/dbus.socket.in +++ dbus-1.12.20/bus/dbus.socket.in @@ -1,5 +1,9 @@ [Unit] Description=D-Bus System Message Bus Socket +# Do not stop on shutdown +DefaultDependencies=no +Wants=sysinit.target +After=sysinit.target basic.target [Socket] ListenStream=@DBUS_SYSTEM_SOCKET@ ** Affects: dbus (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936948 Title: Dependency loop via sockets.target To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dbus/+bug/1936948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
