On raspberry pi 4b bookworm, error at building

[SpaghettiMonkey]

I'm trying to build from files I had on windows beforehand, changed the env paths accordingly to my new setup, installed docker and docker compose plugin (found no mention of docker compose installation on docker's website so thought that plugin has to be it). From My main folder, I'm now trying to build, and this is what I get :

szuru $ sudo docker compose build
