{{Admon/tip|Problems Encountered When Running Yum Command|Sometimes students may experience problems when performing updates when using the '''yum''' command. Sometimes there may other processes that are running the yum application: you can check for this by issuing the <code>'''ps aux'''</code> command, and kill the process. Also, it is highly recommended to issue the command: <code>'''yum clean all'''</code> to perform a reset and clean up repository data.}}

<li value="8">Based on the result, do you think that cups is a useful package for your system? If not, try removing it.</li> <li>Issue the command: <code>'''yum repolist'''</code> . What do you think this command does? Why would this type of information be important for you as a Linux administrator?</li> <li>Unused and unneeded software can present a security risk and ties up disk space needlessly. Find at least 4 other packages that you're not using on your system(like '''sound and video''' applications), and remove them. Be careful to ensure that removing those packages does not also remove other software that you do need.!</li>
