After installing Linux the first thing users do is to update their Linux system following the prompt by the update manager on the task bar.

My advice is don’t  do it,especially if you are a beginner or have installed an Nvidia driver. The drivers are compiled specifically for your system. An update will change the nature of your system. Therefore the drivers may not work properly with an updated system and new users might think that their system has crashed!!. So please update only if their is a genuine problem or only if you are an advanced user !

Get used to the feel of the current system then change it.

The motto of the story is “If it ain’t broken don’t fix it “
