I upgraded from 13.10 to 14.04 and now the nm-applet no longer shows in the system tray. I already tried purging and reinstalling the network-manager-gnome package but that didn't help. When I run nm-applet manually in the terminal I get the following output:  ** (nm-applet:7419): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-gBrnqcTAVj: Connection refused   I tried multiple system trays: i3bar (my default), trayer and the xfce4-panel. Other tray apps work in all three of them (like dropbox). The network manager itself works, as it connects to known networks and outputs notifications. Does someone know how to fix this?

I have a Lubuntu (now 14.04) installation. Recently, I logged in to find that the Wi-Fi icon had disappeared, and there was some sort of a keyboard icon in it's place. I have restarted multiple times, but it doesn't fix it. I can't find the same applet in the panel settings, and resetting the panel didn't help. When I try to manually start nm-applet, it starts, but prints a bunch of warnings to the console:  nm-applet-Message: using fallback from indicator to GtkStatusIcon   It then starts, using ugly icons for the Wi-Fi connectivity symbol.  What do I need to do to make it start correctly? Once it starts, why isn't it using the right icons?

When I started my laptop, there was no network service, and also no network icon in the top bar. It gives an error when I start OS like "Sorry, Ubuntu 14.04 experienced an internal error". When I click details, it says the error is occurred in the executable path usr/sbin/NetworkManager. Also, when I try to enter Network in the System Settings, it says "the system network services are not compatible with this version"  How can I solve this shocking issue?  p.s. I didn't install any third party packages/apps related with networking. Only system updates are installed.

I hope you can help me. I installed Ubuntu 18.04 a few days ago and, while trying to configure it and installing new packaged and software, I think I did something bad. I think it could be related with installing python. Anyway, netiher the gnome-terminal or gnome-tweaks can´t start anymores. Also, when I try to update (sudo apt-get update) it gives me the following error:  sh 1: /usr/lib/cnf-update-db: not found Reading package lists... Done E: Problem executing scripts APT::Update::Post-Invoke-Succes 'if /usr/bin/test -w /var/lib/command-not-found -a -e /usr/lib/cnf-update-db &gt; /dev/null; fi' E: Sub-process returned an error code   I am relativeley new to Linux so I have no clue how can I fix this. Any idea? Even to restore defult configurations/settings?  Thank you very much!

I have many applications with tray icons like davmail, hardware monitor. I miss this feature on Ubuntu 14.04. Does anyone have a solution?  There are some tools like Skype indicator, but I need a general solution for this problem so that I can add application icons to the system tray.

While upgrading to 14.04 using sudo do-release-upgrade my network connection was interrupted and several packages failed to upgrade.  Running do-release-upgrade again reported No new releases found but apt-get listed many packages "kept back", so it seemed the system was in an intermediate state. I ran apt-get dist-upgrade which installed those packages again, then apt-get autoremove after which apt seemed happy.  However, after restarting I cannot log in at the GUI prompt. After entering my password the error "Failed to start session" appears in red. I am still able to log in from the command prompt, but I don't know what to do to solve or debug the GUI log in failure.

Unfortunately, I uninstalled network-manager-gnome using sudo apt-get remove --purge network-manager. I was trying to reinstall it from but without internet connection I cannot do so. What is the solution for this?

Just updated the mountain lion, and download the latest Eclipse 4.2 to upgrade the old one. However when opening the application, it shows that it is from an unidentified developer and the gatekeeper refuses to open it.  I know that there is an option to change the security and privacy option to allow it, however I want to know whether there is a way to just add eclipse into the list. Any hint on this?  More information: before updating I have the Eclipse 3.7.2 on machine, and after updating it works smoothly (I think I have added it into the allow list). So is there a way to do this to Eclipse 4.2?  Thanks in advance!

I used to be able to share my network connection by editing the Auto Eth0 to share with other computers in the Ipv4 section and now I upgraded my laptop to 11.10 .  Now are there no wired connections in the network manager.

About 10 minutes ago I set up my basic Terminal app to be semi-transparent and was really happy with the result. Now, some updates ran and the whole "Background" tab is gone from Terminal settings. Was this option removed? If yes, why? Why would anyone do that?  I'm running gnome-terminal 3.10.2 from the Gnome3 ppa.

I'm wondering how it's possible to remove the little mail indicator applet in the global menu. I've uninstalled all the programs that use it, like Thunderbird, Empathy, and Gwibber, since I don't use any of them, but the icon is still there.  Any ideas?

Yesterday I upgraded my Ubuntu by SSH but before I finished it, I restarted my computer. I know that was not very smart. Anyway now I don't have internet connection, the WiFi or Ethernet is not recognized.  When I try on the latest version installed, the mice didn't work. When I try with previous version and go in gnome-network manager it's said:     The system network service is not compatible with this version   Another thing is when I comeback to the remote computer and look at the SSH terminal the process have stopped at:  Setting up desktop-file-utils (0.20-0ubuntu2) ...  Configuration file `/etc/gnome/defaults.list'  ==&gt; Modified (by you or by a script) since installation. ==&gt; Package distributor has shipped  an updated version. What would you like to do about it ?  Your options are: Y or I:install the package maintainer's  version N or O : keep your currently-installed version D :  show the differences between the versions Z : start a shell  to examine the situation The default action is to keep your  current version. * defaults.list (Y/I/N/O/D/Z) [default=N] ?  Write failed: Broken pipe   Is there any simple solution other than I having to reinstall my system?

I've installed Skype, but the icon is not shown at the top panel (tray). As "tray-whitelist" was removed from dconf, I can't add icon by myself.

I tried to post to this thread  for if I understand their question I am having the same problem, but the answer option won't work for.  After suspend, the wireless is disconnected and the only way to get it to reinitialize/be recognized is to do a full restart.  At first I thought it was my gnome-shell (for lock screen disappeared there with 13.10), but when I switched to the default Ubuntu it's still doing it and it's kinda driving me nuts for I have to reopen all my files and browsers/tabs/windows every time. I don't know how to show the terminal stuff the above asker shows, but it sounds like the same issue and it only started with 13.10 upgrade a few days ago.   Any help would be much appreciated!!! -- Thanks so much, ser.

I have Ubuntu GNOME 14.04 LTS and from installation, my name has not appeared in the panel. I have enabled it via dconf in org.gnome.desktop.privacy, but it has yet to appear even after a re-login and restart.  Can I receive some assistance into the cause of this and a solution?  This is where I would like it to appear:
