  • click it. What does it say? – Tim May 01 '16 at 13:20
  • In the launcher bar on the left have you got the new 'Ubuntu Software' item ? (Not to be confused with old 'Ubuntu Software Centre', which if you upgraded to get 16.04, came from an older Ubuntu version and has the same design of icon) If you have the new 'Ubuntu Software', click it and select the 'Updates' tab, click it and see what's available. – NickT May 01 '16 at 13:41
  • You have installed `chrome` in some strange way, without the required security keys. I would advise to uninstall chrome and the installing it again (the same for this "talkplugin" that I do not know). – Rmano May 02 '16 at 14:49

It could be an error relative to some broken updates.

You can try to fix this error updating package list:

sudo apt-get update
sudo apt-get upgrade

Note: before run the above commands check that your computer is connected to internet.

I hope this could help you.
