update-manager crashed with RuntimeError in <module>() : RuntimeError: could not open display.It should display a warning when $DISPLAY is not set.

Thanks for your bugreport.

The crash indicates that update-manager can not connect to your display for some reason. How do you start update-manager? Is this reproducable in any way?

Closing this bug report as no further information has been provided. Please feel free to reopen this bug if you can provide the information asked for. Thanks!.

This affects the beta of Karmic to.

I'm a new user, i had trouble upgrading to ubuntu 9.10 when KDE was set as default desktop, i was able to reset to gdm & upgrade proceeded however upon boot i had a black screen without any options.

Using recovery mode, i tried to reinstall xubuntu, kubuntu desktop & desktop managers separately & then eventually installed edubuntu & used the recovery to repair broken packages.

I was then able to boot gui with loads about 3/4 startup crashes.

root@ubuntu910:~# lsb_release -rd
Description: Ubuntu lucid (development branch)
Release: 10.04
root@ubuntu910:~#
trying to upgrade
update and dist-upgrade stuff.
I run update-manager -c -d from terminal and also through gdm.

Miked,

The crash file shows:
 Traceback (most recent call last):
   File "/usr/bin/update-manager", line 43, in <module>
     gtk.init_check()
 RuntimeError: could not open display

This indicates that update-manager can not connect to your display for some reason.
When you reproduce it, what is the output of the command:
$ echo $DISPLAY

If you're upgrading from a console use the command 'do-release-upgrade' instead.

On [F1] Terminal I get a blank.
root@ubuntu910:~# echo $DISPLAY
root@ubuntu910:~#
On [F7] Terminal I get:
root@ubuntu910:~# echo $DISPLAY
:0.0
root@ubuntu910:~#

Thanks for the new do-release-upgrade command.

O.K. Here is what is happening.
I start my computer, Ubuntu loads up and auto-logs on and in. Since it loads up a user that probably doesn't have sudo rights. I open up another terminal to access root. [F7] Terminal to [Ctrl]+[Alt]+[F1]Terminal. Then I run commmands like: sudo apt-get update, sudo apt-get upgrade, sudo apt-get dist-upgrade, and sudo update-manager -c -d. I understand I could do that from a terminal window, I perfer to use this method for public access computers being upgraded real-time, while users continue to use the machines.
When I type the command: sudo update-manager -c -d from the console while a [F7] Terminal is open in the background, I get this error message, and a bug report is produced.
I expect to be able to open up multiple terminals with or with out gdm, startx, or whatever gui interface, on more that one terminal at a time.
Thanks, let me know if i'm expecting to much, or if there is a better option for upgrading real-time and sending it to background, so it doesn't bother no sudo users.

Thanks for your feedback. Because update-manager is a GUI application it needs an xserver and the environment variable DISPLAY determines how it should connect to that server. There is no DISPLAY set by default on a tty and update-manager is not intended to be launched from a tty unless you know what you are doing.
So I'm closing this report because it's not a bug in Ubuntu. Thanks.

Thanks,
So it may not be a bug, but it does make a bug report and give a unuseful error message to a user, so something might be changed to let a user know to run it from a gui and not from the tty. Why doesn't it open a new instance of gui or a display on that terminal ? I probably have the commands wrong I understand, and don't always know what I am doing, just a suggestion.

You're right miked, and it seems to hit many users. Changing the status accordingly.
Thanks.

i have this issue, is there a fix or can I help in any way?

I would like to point out that when I got this bug I was on Ubuntu 10.10 upgrading to 11.04. Ever since upgrading to 11.04 I have not been able to reproduce the bug.

This bug is stopping me from upgrading, how do you work around it?

found solution, do not put the code below

: Sudo update-manager -d

just open a console session using terminal and with out getting root, just type "update-manager -d" (without the speachmarks).

Worked first time this way.
