Chrome shows two icons in Unity Launcher [duplicate]

Solution 1:

I periodically run into this problem and variants of it, most recently on Ubuntu 14.04.

Here's what has worked for me in these cases:

1. Close all Chrome windows (and choose Exit from the Chrome indicator menu, if you have one).
2. Right click on all Chrome icons in the launcher and choose Unlock from Launcher.
3. Open the Files application.
   1. Choose Location from the Go menu (or press Ctrl-L).
   2. Type .local/share/applications into the text field and press Enter.
   3. You should see a number of files whose names contain "chrome" (or "chromium" if you're using Chromium instead of Google Chrome. Send these files to the Trash (but leave any other files in this folder alone).
4. (You might have to log out and log back in at this point, but I don't think this is always necessary.)
5. Open the Dash and type chrome. You should see only 1 entry.
6. Launch Chrome and lock to the launcher (by right clicking on the icon and choosing Lock to Launcher or by dragging the icon out to the right of the launcher and then back in at a different location).
7. Close the Chrome window, and then use the launcher icon to reopen it. It should open normally and you should not see a 2nd icon appear.
