So today I had trouble in an upgrade for Ubuntu when I accidentally shut down my laptop. I was able to log in and reset everything but I noticed that the icons on the top right panel are missing (network icon, volume, messages, even the icon launcher and my name). The only way I can switch off my device or even restart is by manually pressing the switch button of my laptop Only the clock has stayed. I tried looking for my settings but when I searched my dash home, none of my applications appeared. No calculator, no terminal etc. The only results that I got were the files I had saved. My upgrade manager have also disappeared.
I tried the unity reset command but nothing happened. Instead, my Google Chrome icon on my left panel disappeared and similarly, I cannot find it in my dash. I'm quite the novice when it comes to Ubuntu so any good step-by-step instructions would be greatly appreciated.
