[Tutorials] Kernel Installation Tutorial: Viewing, Installing, and Uninstalling Local Kernels from the Repository
1. Viewing Available Kernels in the Repository
It is recommended to use:
sudo apt search linux-image-*
This search method provides a more comprehensive list of kernels and is easier to understand.
It is not recommended to use:
sudo apt search linux-image-deepin-*
This search yields fewer results, and the output may not be as easy to understand.
If, after adding the testing repository, you find that the number of available kernels has not increased, run:
sudo apt-get update
to update the repository information, and then check the available kernels again.
2. Installing Kernels from the Repository
Note: The headers and image files need to be replaced with the specific kernel you want to install, which you can copy from the list in the terminal, separating them with a space.
3. Rebooting and Verifying the Installed Kernel Version
After installation, reboot the system and check whether the kernel is correctly installed by running:
uname -r
or
uname -a
4. Uninstalling Unnecessary Kernels
First, check the current kernel version to avoid accidentally uninstalling the kernel in use:
uname -r
or
uname -a
List all installed kernels:
dpkg -l | grep "linux-image\|linux-headers"
or
dpkg --get-selections | grep linux
Select the unwanted kernel for uninstallation.
Note: The headers and image files need to be replaced with the specific kernel you want to uninstall, which you can copy from the list in the terminal, separating them with a space.
