I was installing some apps and icons then I noticed that there were about 4 games installed, so I went to the Software Centre to remove them. Then I wanted to add my Facebook account to Online Accounts but Alas! It was disappeared. But it was there when I searched for Online Accounts in the Unity Dash.

Please help me. I think I might have uninstalled the wrong packages. Can anyone tell me the packages that are associated with them?

Below are screenshots of my settings window and the Online Accounts icon in the Unity Dash.

    The same issue I also have on my Ubuntu 13.10 after an upgrade. – vasiauvi Oct 24 '13 at 14:58
  • What's happen if you run this command in terminal: gnome-control-center credentials? – Radu Rădeanu Oct 24 '13 at 15:57
  • It seems that this issue is only in Unity, because in Gnome-Shell (Gnome 3.8) it's OK. – vasiauvi Oct 26 '13 at 8:20

The solution for me was to install that specific package that was missing:

sudo apt-get install unity-control-center-signon gnome-control-center-unity

    this fixes it in 14.4 – nairboon Jun 16 '14 at 20:37
  • installing unity-control-center-signon did the trick for me. I wasn't able to see online accounts in the search as well as the settings menu. – shivisuper Jun 11 '16 at 3:15
  • Of the two, "unity-control-center" is best given the specific problem originally raised. "gnome-control-center" less comprehensive, but still helpful for other needs. – Brad Horn Oct 8 '16 at 4:52
  • Fixes in 16.10. – Nearoo Oct 14 '16 at 22:33

Try to reinstall gnome-control-center using the following command:

sudo apt-get install --reinstall gnome-control-center

I think I have added the gnome3 ppa in my ubuntu 13.10 for the sake of installing gnome desktop environment but after adding the ppa I changed my mind so I removed it. But before removing it I ran a update, so I think the gnome 3 ppa replaced the online acoounts, appearance, etc etc apps and so I installed synaptic. Go to the gnome-control-center and mark for complete removal and then applied the changes then I installed the gnome-control-center through synaptic and voila it worked. The problem was solved.

But this method a little bit dangerous. Can any expert have a eye on this.

  • That's exactly the same with sudo apt-get install --reinstall gnome-control-center. – Radu Rădeanu Oct 25 '13 at 8:33
  • @RaduRădeanu but this answer is a purge of gnome control center, not just a normal reinstall. – kiri Oct 25 '13 at 9:22

You might have accidentally uninstalled the ubuntu-desktop meta-package.

Reinstall it with the following command in a terminal

sudo apt-get install ubuntu-desktop
  • ubuntu-desktop?!? That's gnome-control-center for sure. – Radu Rădeanu Oct 25 '13 at 8:39
  • @RaduRădeanu so what if it is (please elaborate)? It is possible the ubuntu-desktop package was uninstalled and this would fix it. – kiri Oct 25 '13 at 9:17
  • If ubuntu-desktop would have been removed, those images from the question would have looked completely different. You can try if you are curious. See also apps.ubuntu.com/cat/applications/ubuntu-desktop – Radu Rădeanu Oct 25 '13 at 10:35

sudo ppa-purge ppa:gnome3-team/gnome3

ubuntu 13.10 doesnt work correctly with gnome 3.8
