Assistance Required with Seeed SOM STM32MP157C Linux Image and Ethernet Configuration

Hi there,
I have acquired an STM32MP157C board, and my goal is to install Linux on it and establish an Ethernet connection. I downloaded the Linux image file from the official website at the following link: ODYSSEY – STM32MP157C | Seeed Studio Wiki and installed it. However, it appears that the file is quite outdated.
When I run the sudo apt update command or attempt to install any software, such as Git, I encounter errors, making it practically unusable. I have conducted extensive research in an attempt to find another suitable image file, as I am new to Linux and need an image that is compatible with this board, but I have been unable to find an appropriate one.

Can anyone provide me with a reliable image file or offer guidance on how to set up the board and use Ethernet?

I also uploaded a screenshot providing further details regarding my explanation

Thank you in advance for your help
