Now that you’ve toured the web console, lets work through updating the system.
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.
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
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.
Once you are finished reading, click the
Install Security 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:
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:
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.
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.
Next, let’s take a look at automatic updating. There is an
Automatic Updates switch, at the top of the updates window.
Click on the switch, next to the
Automatic Updates label. You will then see a message, telling you that the package
dnf-automatic is needed:
Install button, to proceed.
dnf-automatic package is installed, you can choose which updates to install, which days, and what time:
You can select from the available menus, and select any combination of the following options:
|Which updates?||What day?||What time?|
Set the automatic update mechanism for Fridays, to apply security updates, at 03:00.
With this simple change, your system will always be up-to-date on critical security fixes, without you having to lift a further finger!
