probably one of the most popular Linux distributions out there, and hence a good choice for learning how to manage updates on. Managing updates on Ubuntu is really pretty easy. If you come over here in the list of icons, you can see that there's an option here called Software Updater. If I click it, it will tell you that updated software is available for this computer, and it asks whether you want to install it now. You can come down here and expand details of updates, and you can see each of the individual updates that need to be downloaded and installed on the system. Now for the most part, you'll want to install all of the available updates as soon as they are available. If, for some reason, there was a particular update that you didn't want to install, you can go through this list and deselect the corresponding check box, and that will prevent that update from being downloaded and installed. But usually, that's not a good idea. Usually you want to install all the updates as soon as they are available. So I've gone through, I've reviewed my list of updates, I've identified that these are the updates that I want. If I come over here to the Settings button, I can configure how I want updates to be installed. I can specify that I want to install updates for security updates. I can install recommended updates. I can install unsupported updates if I want to. I can even install pre-released updates, which I usually don't do, because I want to wait for somebody else to find the bugs in the updates before I do.

So I turn that option off, but I leave these other three options on. Here I can specify how frequently I want to check for updates online. By default it's going to be set to daily. Then I specify how I want to be notified. If there are security updates available, security updates being the most important, then I want those to be displayed immediately. For other software updates, the default is to display weekly,however, I could change that to display immediately if I wanted to, that way I will know at least dailywhat new updates are currently available. We'll go ahead and click Close with those changes made.And at this point we can go ahead and install updates. I do have the option to postpone the updateby clicking Remind Me Later. If you're working on an important task and you don't want your system bogged down installing updates, you can use that option. Usually, though, you want to just go ahead and hit Install Now. This brings up a very important point. Notice that I have about 274 megabytes of updates that need to be downloaded and installed. If you stay on top of your updates, and install them as they come available,which is one of the reasons why over here I wanted to be notified immediately whenever there are other updates available, then the update process really isn't that bad. It only takes a few minutes to complete. If on the other hand, you put it off, and you only install updates like once a month or once every other month or longer, as I've seen some people do, then the update process can be very, very laborious. It can take hours to complete. But if you keep on top of it and install the updates as they become available, it usually isn't that bad of a process. Let's go ahead and click Install Now. And we do have to authenticate with root-

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
