During this process, I actually perform the process of clearing the old Kernel on ubuntu.

automatically remove

The command below can automatically remove unused Kernels.
sudo apt autoremove
 

​​​​​​Manual removal

1. View the Kernel in use
uname -r
View the currently used kernel, such as my current Kernel
4.4.0-104-generic

Do not remove the Kernel in use!

2. View all kernels in the system.
dpkg --list | grep linux-image


3. Remove unwanted old versions of Kernel
I want to remove multiple brace expansions that can be used in bash.
sudo apt-get purge linux-image-4.4.0-9{2,6,7}-generic
The command above removes three at a time.
linux-image-4.4.0-92-generic
linux-image-4.4.0-96-generic
linux-image-4.4.0-97-generic

If we only want to remove a specific kernel on the system.
sudo apt-get purge linux-image-4.4.0-93-generic

4. Update grub2. (linux boot loader)
update-grub2

5. Restart the system
reboot
