Exercise 1.3 - Managing Updates Using the Web Console

Return to Workshop

Exercise Description

Now that you’ve toured the web console, lets work through updating the system.

Section 1: Basic Updating

As you did in the previous section, navigate to the Software Updates section of the Web Console, by clicking on the Software Updates link, in the left-hand menu. There will then be a brief interval where Refreshing package information will appear, along with a progress bar. Once that completes, you can proceed with the exercise.

Step 1: Check for available updates

Take a look at the Available Updates section of the browser window. You should see several packages listed, in a single group, like this:

You can expand the list, to see more details, by clicking on the drill-down > link:

Figure 2: Expanded Updates

In the expanded view, you can see details on what CVEs are relevant to the updates, and any associated bug IDs. Additionally, a summary of the changes is displayed.

Step 2: Install updates

Once you are finished reading, click the Install All Updates button, to install the updated packages.

The updates will install, and while doing so, there will be information on what actions are taking place, and below that, an expandable log drill-down. Once complete, you may receive a window like this:

Step 2: Restart the system

Click the Restart Now button, to reboot your managed host, and cause the changes to take effect. You will see screens like these, while the system is rebooting:

Step 3: Reconnect

Wait for a couple of minutes, for the system to come back up, and then click the Reconnect button, to be returned to the login screen, for the web console. Login, as before.

Step 4: Summary

Once you are logged back in, you will again see the updates screen, with a list of the updates that you just applied. You can expand the history list, to see the details.
