I also have this bug, I'm using kde on my samsung chromebook with crouton. Here
is the command lines when starting.
Entering /mnt/stateful_partition/crouton/chroots/precise...
Failed to start message bus: Failed to open

I have this bug with a recently updated Kubuntu. None of the proposed
solutions seems to work: I do not have the funny quoting in
/usr/bin/startkde, and I am not missing the qdbus executables. I have
both qdbus and qdbus-qt5 installed, both x86_64.

A better fix is to run:
sudo apt-get install qdbus
This will remove an existing 32-bit package and replace it with 64-bit.
After running this, it worked fine for me without needing to change the
quotes in startkde.

I do not understand why this bug is still present!!! I upgraded from 12.04 to
14.01.1 right after the point release. After the upgrade I couldn't start KDE
because of a buggy startkde script. Yesterday I upgraded again this package and
startkde is still buggy!
In line 'alias qdbus=QT_SELECT=qt4
Solution in #32 worked for me after an upgrade like #34 and seems to
explain the problem, but it's obviously a workaround.

Hi,
I can confirm the bug is there upgrading Kubuntu 12.04 to 14.04 on a 64bit
system.
I could work around with (as #29):
sudo ln -s /usr/lib/i386-linux-gnu/qt4/bin/qdbus /usr/lib/x86_64-linux-
gnu/qt4/bin/qdbus
The directory existed already.
It seems there is no qdbus for x86_64-linux-gnu

KDE desktop login failure: Could not start d-bus. Can you
A week before I upgraded my Desktop (64bit) to Kubuntu 14.04. When I restarted,
I could and can no longer get a KDE desktop - wether my desktop with Password
nor the guest-desktop. Instead, I get a window with the message Could not
start B-bus, Can you call qdbus?, and when I click OK, I get
Some details may have changed since April, but the problem remained.
After upgrading to Trusty yesterday, I got the same unpleasant message
with qdbus. In my /usr/bin/startkde file, the crucial line reads:
alias qdbus=QT_SELECT=qt4 qdbus
After removing the quotes, KDE launched successfully, but
FYI I had this problem today (installed some updates recently) and my
system refused to login after rebooting today. Removed the double-quotes
as mentioned above and it's working now. Thanks.

The fix in #12 is utterly wrong.
You can't absolutely use an unquoted space in an assignment:
http://www.tldp.org/LDP/abs/html/varsubn.html#EX9
The reason because it *seems* to fix is luck, the line:
qdbus=QT_SELECT=qt4 qdbus
Would start qdbus anyway, but without the QT_SELECT variable and
I think we have already established that. The issue presented by this
bug report cannot login is resolved, any further discussion on the way
it was resolved should be done elsewhere as it just pointlessly spams
people's inbox. Thanks.

I made a bugreport like this one at about same time ( #1304856 ) anyway

got this output:

[Po]lentino,
That informaion isn't actually helpful. You tried to run qdbus from a
tty without X11 server?
If so, the essage just tells you that X11 should be started and $DISPLAY
env variable should be set in order to call qdbus.

it seems to me the following syntax:
A=B=C D
in dash will execute D with the environment variable A set to B=C,
so the line:
qdbus=QT_SELECT=qt4 qdbus
would run qdbus once, and set qdbus to QT_SELECT=qt4 qdbus:
$ qdbus=QT_SELECT=qt4 qdbus
:1.0
com.ubuntu.Upstart
...
org.freedesktop.DBus
$
It is true that removing the quotes in the line
qdbus=QT_SELECT=qt4 qdbus
Gets around Could not start issue. However, a better fix would be to leave
the quotes in place and further down start up qdbus with an eval statment:
qdbus=QT_SELECT=qtr qdbus
...
if eval $qdbus /dev/null
Nah, that would bring back another issue which was to be originally
resolved by tempering with the qdbus code to begin with.
I am going to prepare a proper qdbus invocation tomorrow.
