After the installation is complete, restart the ubuntu system and use the command uname -r to view the current version number
The kernel upgrade was successful.
Fourth, encounter problems and solutions
Appeared during installation
solve:
You need to install the package libssl1.1. If you use the command directly, the installation will fail. You need to add the source. The update data of this package can only be updated from sources officially recognized by ubuntu.
Go to this website to view https://packages.ubuntu.com/bionic/libssl1.1
Choose the one corresponding to your own system
Add the official source to source.list,
Use the command to open the file sudo vi /etc/apt/sources.list
Save and exit, update the source sudo apt-get update, then you can install libssl1.1, enter the command sudo apt-get install libssl1.1 in the terminal and execute sudo dpkg -i *.deb again. Successful installation.
