Installing a kernel is generally the same as installing anything else that you root install.
There are just two things to remember:
The Linux kernel comes in four parts:
So, when you go to get a Linux Kernel package, always be sure to get and install all four.
The second thing to remember is to update the system after you finish the installation
Now… Let’s look at how to install the kernel and where you can get your packages.
Here is the complete list:
Let’s look for 5.5 first:
In order to stay organized and keep things simple, once you have downloaded each package, just create a new folder in your ~/Downloads folder named “kernel” and place all four of the above packages and only the four above packages in that folder.
Go into that folder in your file manager and open a terminal OR us the ‘cd’ command in terminal
Then use the command to install:
sudo dpkg -i *.deb
Then your update to apply new kernel
This spares you from trying to install each individually in the Correct Order. It also keeps the copy of the kernel in a safe and easy place you can find or remove afterward.
Your English is quite good. It is a shame on me that I speak only one language (Or at least only one actively used language).
