    Had this happen to me tonight on both of my laptops. Solution:

    Ctrl+Alt+F1 to drop to a console. Log in. Type:
    Code:
    sudo apt-get update && sudo apt-get dist-upgrade
    When it all finishes, Ctrl+Alt+F8 and login.

      Hmmmm. Now there's an update for libqt5core5a, libqt5dbus5, libqt5xml5 packages, which I've installed manually in an attempt to fix this qdbus trouble.

      I don't know... I think I'm going to wait for final release for updating again. Too many issues with Beta 2 this time.

        mmmm.... the problems must be machine dependent. The updates in recent days have not given me any problems.... so far.

          I'm not sure "fixed" is the correct term for the solution. A line like the one in which the quotes are removed is probably not doing what the developers intended. But, it does remove the nasty xmessage window saying the qdbus could not be executed.

          qdbus=QT_SELECT=qt4 qdbus

          sets an environment variable for the qdbus program that executes on the line. The environment variable is "qdbus". It's value is "QT_SELECT=qt4" and qdbus is executed. Later in the script $qdbus is expanded but this does not execute qdbus. A better solution is to leave the quotes in as they were and every time qdbus needs to be executed, replace it with

          eval $qdbus

          I have put a comment in the incident explaining that their "fix" is not really a fix. It just allows folks to log in.

              I must say that I am puzzled by many still having problems with not being able to login and getting the dbus error. My system was fixed in this area by updates after less than a 1 day of first getting this error. I am not sure if this is machine dependent or a package option issue. I tend to take a chance by having all package options selected in Muon. This is shown in the attached graphics. I am not sure if this is relevant or not.

              Edit:
              I have been away for about a week and the dbus happened during this time and it was soon fixed as the group I was with were pleased to see a presentation of pictures that I had taken during this time. I have now returned and installed all the updates on another computer with 14.04 and all is working without a hitch.
