What is the general idea to do a kernel upgrade in order to apply the most recent security patches?
I successfully installed Ubuntu-22.04-Desktop-SDBoot-update-MT7351SW-DSA-20220623.zip and it works fine. The image installs the kernel linux-5.10.66. How could I install the most recent security fixes, e.g. currently linux-5.10.143 . I did apt-get upgrade and then tried GitHub - BPI-SINOVOIP/bpi-tools: tools for Banana Pi . Without arguments bpi-update tries to download an image file for a BPI-M2. Are there specific arguments that I need to use ?
Do I possibly need to use the linux-4.19.xx release image to get current security fixes or do I need to / can I compile and install the kernel myself? Is GitHub - BPI-SINOVOIP/BPI-R2PRO-BSP: Supports Banana Pi BPI-R2PRO-BSP a good starting point for doing so, does it contain instructions, or are there instructions elsewhere (I found instructions for older boards but I am not sure if they still apply)?
