so I wanted to install a dock bar called "docky". It, didn't work because I had to do the command sudo apt-get update but I get this output:

I don't know how to fix this. Did anyone have the same issue?

You can add the key for the virtualbox ppa like this:

wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

Source, and more info at https://www.virtualbox.org/wiki/Linux_Downloads

If you don't want or need the virtualbox ppa on your system, you can remove it by opening "Software and Updates" and unchecking it on the "Other Software" tab.
