I am interested in using the provided Dockerfile but when try building the image from it, I face the following error:

E: The repository 'http://security.debian.org/debian-security bullseye-security Release' does not have a Release file. E: The repository 'http://deb.debian.org/debian bullseye Release' does not have a Release file. E: The repository 'http://deb.debian.org/debian bullseye-updates Release' does not have a Release file. The command '/bin/sh -c apt-get update && apt-get install -y git' returned a non-zero code: 100
