ubuntu 12.04 LTS 64-bit missing gear icon after update

After a Ubuntu Update, I am now missing the gear icon in the top right corner. The right two-most icons are "sound" and "Time and Date Settings".

Ubuntu is running in VMware on Windows 7 Home.

Note; Prior to this update I tried an upgrade to 14.04, but the message said that my laptop would result in poorer performance, so I declined.

Note: Prior to the Ubuntu update, I updated VMware and installed the latest VMware toolbox.

I did find this, but not sure whether it works or how safe it is:

sudo add-apt-repository ppa:jconti/gnome3
sudo apt-get update
sudo apt-get install indicator-applet-complete
sudo reboot

Open in new window

In general, when I see advice to add a repository, how do I know whether or not the repository is safe?

That's a good question, usually it's best to stick to the better known ones like Epel and obviously all the standard Ubuntu repos... Normally (hardly any normal user does this) you should check the ppa each time you renew the repository and want to install an update ...

There's an initiative called the SafeRepo that might help in giving more info.

Thanks. After getting the icon back, I did the following:
sudo apt-get install ppa-purge
Then I purged the ppa:
sudo ppa-purge -d <Ubuntu version> ppa:<the PPA to purge>
sudo apt-get update
Then I removed the ppa.
The gear is still there.
