You don't need to update it to complete your problem sets. update50 will take care of the necessary updates. If you are done with your problem set. you can download apache, mysql, php7, phpmyadmin to your computer. It will be a good practice as well. Beside that if you are using the IDE from the cloud I don't think you will be able to make any changes to the core of the IDE because it's not located on your computer.Else, if you are using it on docker I suggest you watch the seminar on week 12 about containers and docker. Hope this helped and please accept my answer if it did.
