(Solved) Installing MESA packages from backports - did not find extension DRI_Mesa version 1

[DTEAM]

Hi, I played with Debian Backports on my Pi5 (big stupid mistake exepted for CMake) and now I have an issue with Mesa. I have read a thread about this issue, but i don't have the permission to delete some files in the usr/lib/ folder.

I already deleted the Mesa packages with sudo apt remove <package>. Any idea to fix this iisue? I'm a little bit in trouble.

NEW EDIT: Here's the list, only Mesa stuff, cmake, pipewire and gir1.2 was intall . I'm not able to go back to 23.2.1 . What is the best way to do that?

Here's the error message

Solved

I used this line to see the versions of the packages and know which one I want to change to

dpkg-query -W | grep '~bpo'

after, I purged all I wanted

sudo apt --purge remove libgl1-mesa-dev
sudo apt --purge remove libsdl2-dev 
sudo apt --purge remove libgl1-mesa-dri

and more  .....

If you use sudo apt remove libgl1-mesa-dev instead of purge, it's not enough. That was my mistake.

After I loaded Retropie-Setup

sudo sh ~/RetroPie-Setup/retropie_setup.sh

and I re-installed all dependency packages

For someone with basic computer skills like me , I had a close call!! 🤣

For CMake, what I did works well, but I don't recommand to play with that without a backup!
