Crouton: Error When Starting Xfce Linux Session (dbus error)

[AlexObliv2029]

Please paste the output of the following command here: sudo startxfce4 Failed to start message bus: Failed to open "/etc/selinux/targeted/contexts/dbus_contexts": No such file or directory
EOF in dbus-launch reading address from bus daemon
/etc/xdg/xfce4/xinitrc: 1: /etc/xdg/xfce4/xinitrc: ssh-agent: not found

* (xfce4-session:19058): CRITICAL *: Unable to contact D-Bus session bus: Unknown error

* (xfce4-session:19058): CRITICAL *: Unable to contact D-Bus session bus: //bin/dbus-launch terminated abnormally with the following error: EOF in dbus-launch reading address from bus daemon

Please describe your issue: I just recently installed crouton, but when attempting to open a Linux session receive the error above. Please help.

If known, describe the steps to reproduce the issue: Run xfce on Samsung Chromebook 3

Please post the output of: sudo edit-chroot -all

Hello, I am running into the same error on an Acer Chromebook 14:

chronos@localhost / $ sudo edit-chroot -all
Password:
name: precise
encrypted: yes, locked
Unmounting /mnt/stateful_partition/crouton/chroots/precise...

Sorry about the output formatting, to me, it displays better (recognizes carriage returns) when using 'insert a quote' instead of 'insert code' I am very new to Linux and Unix and GH, but am very excited to be tinkering around with a Chromebook and Linux.

Here is what I get for the initial output of the sudo startxfce4 command. Later on, i see the same messages that Alex posted above.

chronos@localhost / $ sudo startxfce4
Enter encryption passphrase for precise:

You'll have to enter your password to unlock your chroot before we can see what crouton version you're using.
Another way is to get into your chroot and then show us the output of croutonversion.

[10BaseTwo]

Dennis, thank you for the quick reply, and sorry for my ignorance. I hope I'm running this the way you have asked, but I feel like I am still doing something wrong. I did enter my password to run the sudo cmd the first time, then ran it again in a few other directories.

chronos@localhost /mnt/stateful_partition/crouton/chroots $ sudo croutonversion
sudo: croutonversion: command not found
chronos@localhost /mnt/stateful_partition/crouton/chroots $ cd /
chronos@localhost / $ sudo croutonversion
sudo: croutonversion: command not found
chronos@localhost / $

This was the beginning of the install I did earlier tonight using sudo sh ~/Downloads/crouton -e -t xfce

looks like I might have downloaded version 1.0.87

@AlexObliv2029,

No problem.

chronos@localhost /mnt/stateful_partition/crouton/chroots $ sudo croutonversion

Don't use the 'sudo' prefix inside your chroot for crouton stuff, that'll get you into trouble with permissions, just use 'sudo' outside your chroot for crouton stuff in your crosh shell.

---

Let's please start over with something that works better.

First of all delete the chroots you've started that don't work using -

cd /usr/local/chroots ; sudo delete-chroot * ; cd

Then instead of 'precise', we'll install a newer release but we won't encrypt it to make it simpler, if you really want to encrypt it you can do that later, use this -

sudo sh ~/Downloads/crouton -r trusty -t xiwi,xorg,xfce,keyboard

Then install the 'crouton integration' extension from the Chrome Webstore.

Now you can start your xfce4 desktop in a number of ways -

1. sudo startxfce4 (that will launch in a window via 'xiwi', the default)

2. sudo startxfce4 -X xiwi-fullscreen (that will launch fullscreen via 'xiwi')

3. sudo startxfce4 -X xiwi-tab (that will launch in a browser tab via 'xiwi' - my favorite)

4. sudo startxfce4 -X xorg (that will launch in a separate screen via 'xorg')

Please note, the last option using 'xorg' is having some temporary difficulties (blackscreens) so it may not work for you without some extra effort.

Hope this helps,
-DennisL

DennisL,
I'm having the identical issue. I will try your suggestion and let you know how I make out.

[10BaseTwo]

Thanks Dennis! That worked perfectly for me, I am now up and running. Thanks again for your patience and help!!

@AlexObliv2029 @jhut1971, I hope this works for you!

[jhut1971]

Thank you, all worked for me as well

I am still unable to get it to work.

when I enter:
sudo sh ~/Downloads/crouton -r trusty -t xiwi,xorg,xfce,keyboard

Linux starts; I cam see the terminal prompt change to what I expect a Linux prompt to look like. However, the GUI never starts. I see several "Cannot connect to the extension, retrying ...

Then is says
Unable to start display, make sure crouton extension is installed

I ahve also noticed that when I run this command:
sudo sh ~/Downloads/crouton -r trusty -t xiwi,xorg,xfce,keyboard

I get several messages:
Cannot check release signature; keyring file not available /usr/share/keyrings/ubuntu-archive-keyring.gpg
Retrying failed download of http://archiveubuntu.com/ubuntu/dists/trusty/InRelease

[DennisLfromGA]

@Hasaf,

when I enter:
sudo sh ~/Downloads/crouton -r trusty -t xiwi,xorg,xfce,keyboard

Linux starts; I cam see the terminal prompt change to what I expect a Linux prompt to look like. However, the GUI never starts.

The first 'crouton' command will install your chroot not start a desktop session.
I think you are referring to using sudo startxfce4.

I see several "Cannot connect to the extension, retrying ...

With the 'xiwi' xmethod you also have to install the 'crouton integration' extension from the Chrome Webstore. If you don't you'll get this message:

You must install the Chromium OS extension for integration with crouton to work.
The extension is available here: https://goo.gl/OVQOEt

It's easy to miss these messages sometimes.

I ahve also noticed that when I run this command:
sudo sh ~/Downloads/crouton -r trusty -t xiwi,xorg,xfce,keyboard

I get several messages:
Cannot check release signature; keyring file not available /usr/share/keyrings/ubuntu-archive-keyring.gpg

The 'keyring' warnings are not critical.

Retrying failed download of http://archiveubuntu.com/ubuntu/dists/trusty/InRelease

You may have to re-run the 'crouton' installation command or do a 'crouton' update using the '-u' option.

---

Since you also installed the 'xorg' xmethod you should be able to launch your xfce desktop using:

sudo startxfce4 -X xorg

Hope this helps,
-DennisL

[Hasaf]

Dennis,

Thanks, that was it. I already had crouton integration, I didn't have the correct start command.

Regards,
Hasaf

as far as I know my crouton version is the latest:

[DennisLfromGA]

@jbeale1,

Your issue doesn't seem to be related to this topic but...
A lot of times these are just transient network glitches, try again (and again). :)

---

_(precise)john@localhost:~$_ sudo sh ~/Downloads/crouton -r trusty -t xiwi,xorg,xfce,keyboard

Taking a second look at your command string, it looks like you're trying to install a new 'trusty' chroot _inside_ your 'precise' chroot - not good!
Exit your 'precise' chroot and try again if you like.

Hope this helps,
-DennisL

[jbeale1]

If you browse to http://archive.ubuntu.com/ubuntu/dists/trusty you can see that "Release" does exist, however "InRelease" does not exist. Is this a typo in the install script? Did the name change? Was the InRelease file deleted?

..oh... I notice that more recent distributions like http://archive.ubuntu.com/ubuntu/dists/yakkety/ have both InRelease and Release files. So I guess the missing "InRelease" is a signal that the distribution is old / no longer suported / no longer "In Release" ?

(I may be in the wrong place; I got here from a google search on the failing "InRelease" file which was referenced by another person posting above in this thread.)

hello dennis I'm sorry I want to ask my password can not be pressed in ubuntu how to solve it? I want to use ubuntu to install application on my chromebook
can you help me? can i Ask your facebook address

[DennisLfromGA]

@zaky46,

[ This is way off topic but it's a quick fix so I'll respond. ]

I'm sorry I want to ask my password can not be pressed in ubuntu how to solve it? I want to use ubuntu to install application on my chromebook
can you help me?

Get into your chroot as root using:

sudo enter-chroot -u root

Then run the passwd command for the username you want to set a new password for, somthing like this:

passwd zack

Then enter the new password twice, it won't be displayed for security reasons.
Then exit your chroot and re-enter it again, sudo and other commands should now work with your new password.

can i Ask your facebook address

Sorry, I don't do facebook.

Hope this helps,
-DennisL

Here is what I did and that's resolved my issue.
mkdir -p /etc/selinux/targeted/contexts/
echo '' > /etc/selinux/targeted/contexts/dbus_contexts
This fixed the issue. On my second server I was having the same issue but I changed the syntax a little bit and it just worked fine over there as well.
mkdir -p /etc/selinux/disabled/contexts/
echo '' > /etc/selinux/disabled/contexts/dbus_contexts

Closing. Please update your chroot and try again, re-open if this issue is still a concern.
