Ubuntu 12.04 upgrade destroys network

WantLinuxHelp · 07-01-2012, 04:03 PM

I upgraded my Ubuntu with LXDE to 12.04, and I no longer had any network connection. What should I look at in order to try to diagnose this Ubuntu upgrade bug?

Next place I'd look is to see if NetworkManager is running

Code:

ps aux | grep NetworkManager

If it's not running, start it

Code:

sudo service network-manager start

Next place I'd look is to see if nm-applet is running; if not start it. If it is running, right-click on the nm-applet icon in the panel, and edit your connection

Thanks, RD.

NetworkManager was in fact not running. When I started it, a window popped up saying:

Code:

Sorry, Ubuntu 12.04 has experienced an internal error

executable path:
/usr/lib/notification-daemon/notification-daemon

package:
notification-daemon.0.7.3-1

title:
notification-daemo crashed with signal 5 in g_return_if_fail_warning()

But the network manager is still running, and I seem to be able to get to the network now.

When I reboot, the system takes forever. I see a message saying "waiting up to 60 more seconds for network configuration.". Then it says "booting without full network configuration" When it comes up, no NetworkManager. When I start it, I get the same "internal error" message.

After rebooting the system, I found this is the syslog

Code:

I don't know if this is important or means anything

Thanks. This is a bug for the g_return_if_fail_warning() problem. Since I do NOT get that on reboot, but only upon manually starting the NetworkManager, and since noone else reporting this in the bug report mentions the NetworkManager, I am assuming this is a SECOND problem, and not the reason that my NetworkManager fails to start on reboot.

Now that I have my NetworkManager working, should I file a Ubuntu bug on it failing to start on boot? Which package is it?

It's notification daemon problem also it's in your post #3

I dont think thats a bug though. His network manager quit working because apt shut it down to upgrade it. Then Ubuntu was using the fallback configuration of /etc/network/interfaces to look for a network but nothing was there so he got that error. Once Network Manager daemon started back, it takes precedence over the fallback /etc config is all.

Kevin, thanks. This sounds reasonable. How do I get things working again?

Hi. Actually. Upon looking things over, what you are experiencing has nothing to do with Networking. Apparently it has to do with themes. Like the colors, shades, window borders,etc. From what I can tell Ubuntu switched from gtk2 to gtk3 for version 12.04s. Gtk just stands for Gimp Toolkit I think. It was used in designing the window looks and feel in GNOME and Metacity- Gnomes Window Manager. So my guess is somewhere in your settings in from your old Ubuntu is clashing with the new Ubuntu settings. You said you have LXDE on top of Ubuntu? Or do you have the distibution Lubuntu? I think a theme from LXDE is gtk2 based and Ubuntu 12.04 with all gtk3 doesnt like it. Does any of this sound familiar?

Well, we'll try this cause I think it "may" help you, but not sure. If it doesn't, it can be reversed although these files do no harm at all, and all are official Ubuntu packages in Precise. You just may be missing one or two you need due to lxde being installed. So open a terminal as root and type all of the following in one shot:

Code:

#apt-get update

#apt-get install scim-gtk2-immodule libgtk2-perl gtk-theme-switch Gtk-chtheme gtk-clearlooks-gperfection2-theme Gnome-color-chooser Ibus-gtk lxde-common Lxappearance dbus-x11 libdbusmenu-gtk-doc python-dbus libindicate-gtk3-3 libdbus-java libdbusmenu-gtk4 Appmenu-gtk Appmenu-gtk3 gir1.2-dbusmenu-gtk-0.4 gir1.2-dbusmenu-gtk3-0.4 libdbus-glib-1-2 libnet-dbus-perl jobservice gnome-settings-daemon-dev

Hit enter. It should pull all or any dependencies it needs with no problem. If it gives you an error of any kind, check for simple misspellings in package names, which may be my fault but I was pretty thorough on it. So install all these. When it finishes. Reboot. See if you still get that error message or not. Either way, let me (us) know.

I mean this is what i personally would do and try first

How can you say that? When I boot, my network is not working.

Also, when I reboot the system takes forever, and I see a message saying "waiting up to 60 more seconds for network configuration.". Then it says "booting without full network configuration" When it comes up, no NetworkManager.

LXDE on top of Ubuntu

Maybe this is causing the SECOND problem with the "internal error"

I'm thinking I should make a new thread for that. I'll post the link for the new thread here.

This may be your solution , but you insist that it's not.
