Learn Kali Linux Episode #11: Installing VirtualBox Guest Additions

Hello everybody and welcome to this tutorial. Today, I will continue from where I left off in the previous one. Now if you remember we issued apt-get update and apt-get upgrade commands that took a while to finish and process. I was prompted once, I was given a readme file in regards to wget packet, and the way you handle it is you press Q to exit, you do not close the terminal and terminate the updates rather, instead, you just press Q to exit the readme file, and the update process will continue, no problems. So today we need to configure the sources list. Those are the list of repositories from which your Linux distro actually pulls various packets and information from. Just like Fedora, Kali Linux also has repositories, and if you go onto their website you will see the link is here, I have marked it. You have these 4 repositories that are the default repositories of Kali Linux, and you can just go ahead and copy and paste them. Not a bad idea to do this, and sometimes, I don't know why, I don't find them by default in the repository list and the sources list, so I got to do it manually. You go ahead and basically type in cd /etc.apt/, ls, and there we go you have sources.list. Go ahead and type nano sources.list, press ENTER, and there you are now in the repository file. This is where they are listed, this is where you can type them in. So let's just go ahead and copy these two. I'm not gonna worry about any duplicates now, or anything of a kind, duplicate repositories are not gonna break anything, so no worries. The system is smart enough to realize that for itself. So I'm just gonna go ahead and copy the four of these. Later on if we want we can sort this out and remove the duplicates, or something of a kind, but for the time being it doesn't matter, it's not gonna break anything. Just copy all four of them, press ctrl o, enter, ctrl X to exit, and there you go. So, once again, ctrl o to save a file, so press ctrl o, enter, and then ctrl X to exit. Excellent! Now that we got that sorted out we need to clear the screen, and even though we've actually placed our repositories there it doesn't matter, the system will still not be able to pick anything up from them until we actually perform the following. So we need to do apt-get update. So we're not upgrading the system we're just updating the repository lists.
