Noob here. System is a Lenovo ThinkPad 11e with N2940 Celeron processor (quad-core @ 1.83GHz) and 8GB RAM. This is my first time installing Ubuntu (16.04 LTS) and working with Linux in general. Pictures 3 and 4 are the updating options I have selected. However, when I open the Ubuntu Software application, I am seeing an available update (picture 2)
I am also seeing another available update (picture 1) under the additional drivers tab, yet I'm still a little unsure about it. Again, this is my first time working with Ubuntu or any other Linux distribution. My question is why are there available updates to install if I have selected those options in pictures 3 and 4? Should I install all of these? Are the updates in picture 1 and picture 2 related at all, or are they two completely different things?
Also, In another thread I read to run the commands: sudo apt update && sudo apt upgrade. Would this be the same as installing these updates or is there any difference?
