George Ashby's questions

I have just recently installed Ubuntu onto my new laptop, following all steps correctly during installation, installing new applications and drivers from online. Upon finishing installing Ubuntu, I attepmted to install MariaDB via the terminal by typing:

sudo apt-get install software-properties-common

and then the following error is returned:

sudo apt-get install software-propterties-common
  File "<stdin>", line 1
    sudo apt-get install software-propterties-common
           ^
SyntaxError: invalid syntax

How can i get my termianl to function correctly?

I found the menuentry/subentry that I wanted to use, as you can see here: https://gyazo.com/b73fa2308145caaed7959a95d71a4bc8

I then changed this in /etc/default/grub to this: GRUB_DEFAULT=1>0

I updated grub with: sudo update-grub

And then rebooted the system with: sudo reboot

It still loads into the same old kernal.

I am using Ubuntu 16.04.
