dbus Failed to connect to socket /run/dbus/system_bus_socket: Connection refused

[kafteras]

Hello

There seems to be a problem with dbus in repos..

The following packages have unmet dependencies:
 dbus : Depends: dbus-bin (= 1.12.20-3)
        Depends: libdbus-1-3 (= 1.12.20-3) but 1.12.24-0+deb11u1 is to be installed
 dbus-daemon : Depends: dbus-bin (= 1.12.20-3)
               Depends: libdbus-1-3 (= 1.12.20-3) but 1.12.24-0+deb11u1 is to be installed
 dbus-user-session : Depends: dbus (>= 1.12.24-0+deb11u1) but 1.12.20-3 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

dbus tries to update, but has dependencies that need older version.
And now im stuck with a broken dbus, unable to remove it, install it or start it

Now every vm returns:

/usr/sbin/qm start 103
org.freedesktop.DBus.Error.NoServer: Failed to connect to socket /run/dbus/system_bus_socket: Connection refused

Help please

That's not the output of apt udpate

What if you try apt install dbus dbus-session-bus-common- dbus-system-bus-common-? That would already remove the two packages marked for autoremoval at the same time (because of the trailing - after the package name). In particular dbus-system-bus-common which is causing a conflict when dpkg tries to install the dbus package. Of course don't approve the operation if apt suddenly tries to remove something else you want to keep!

Unfortunately it doesn't want to remove them. Its like a dependency cycle with mismatched versions.

 

[fiona]

Can you try apt install dbus dbus-session-bus-common- dbus-system-bus-common- dbus-daemon-? If it doesn't work, the output of apt show dbus-daemon would be interesting. On my setup, it's a purely virtual package, but for you probably not yet.

Description: simple interprocess messaging system (reference message bus)
 D-Bus is a message bus, used for sending messages between applications.
 Conceptually, it fits somewhere in between raw sockets and CORBA in
 terms of complexity.
 .
 This package contains dbus-daemon, the reference implementation of a
 D-Bus message bus, and dbus-run-session, a utility to start a temporary
 session dbus-daemon in a constrained environment or for automated tests.
 .
 To provide a complete D-Bus session bus, install one of the packages
 that implement the dbus-session-bus virtual package, such as
 dbus-user-session. The recommended implementation is indicated by
 the default-dbus-session-bus virtual package.

That's unfortunate, because apt doesn't get that it needs to do the removal first

EDIT: Also suggested by @fabian : you could try adding -o Dpkg::Options::="--force-overwrite" to the apt command.

@fabian suggested that you could still try doing only the removal first. If that also doesn't work, you'll likely need manual dpkg invocations. But it might be easier to just reinstall the system.

It seems like some of the packages come from a Debian Bookworm or Sid repository, so that's the likely cause of the issue, because downgrading is not supported in general.
