Ubuntu Pro. Why do I need that?

If you are managing your own web server this post is for you.

Sometimes after login to your srever, you can see the annoying message

*** System restart required ***

Documentatin says that Reboot as little as possible, but as often as is required for security.

There is an option to not reboot own server every time

Enabling Ubuntu Pro

sudo pro attach <yourtoken>

### if you dont have the patch you need to install
sudo apt update
sudo apt install ubuntu-pro-client -y

The main benefit for me is

Kernel Livepatch (Zero-Downtime Patching)

Function: Livepatch allows you to apply critical and high-priority Linux kernel security patches while the kernel is running, without requiring a system reboot.
Result: This drastically reduces the number of reboots needed, allowing you to maintain high uptime while staying secure against the most serious kernel vulnerabilities.

sudo pro detach

## optional
sudo apt remove ubuntu-pro-client
sudo apt autoremove
