Ubuntu's Update Manager automatically checks for upgrades to all installed packages on your system.
However, the update schedule can differ from machine to machine.
Many packages in a Linux distribution are updated frequently to fix bugs, add features, and protect against security exploits.
When you first launch and connect to an Amazon Linux instance, you may see a message asking you to update software packages for security purposes.
Windows also has its own kernel that its operating systems use, but Linux is highly modular and therefore the kernel is more commonly discussed as a lot can be done with it.
This section shows how to update an entire system, or just a single package.

Then check to see if the output says x86_64 or i686. This will tell you what the current stable version of the kernel is.
If it’s x86_64, then you’re running the 64-bit version; otherwise, you’re running the 32-bit version. You can try out release candidates if you’d like, but they are a lot less tested than the stable releases.
