Download complete installation files or choose to download just the update versions available.

Installing a new installation of Linux will likely wipe older files even if they are currently in use.

Update your Linux OS by following the prompts as they appear in the update file. Often the installation process requires minimal input from you. The opposite is true if you are including a bundle of applications within the update.
