I'm using a machine that runs on 64-bit Ubuntu 14.04 LTS
I run regular 'System Updates'. On one day after performing such regular 'System Update' my system stopped detecting wireless and wired networks. Then I followed the steps given in following question : Did the steps to enable wireless and wired network detection
My wi-fi and wired network got started working but one red circular icon containing minus sign within started appearing on system tray at top right corner of my screen.
When I clicked on it, a pop-up appeared. From it I chose the option'Install all updates'. Then following pop-up appeared.
Now can someone please help me in running my system smoothly with all the updated packages and get rid off the red circular icon appearing in a system tray?
Thanks.
