Build Error

I use a raspberry PI4 as server when i try to run "./build_server.sh -f armv8.ubuntu.Dockerfile" on ubuntu server 22 i get the following error. How to solve this error?

=> ERROR [base 3/17] RUN useradd -m sdr -u 0 && echo "sdr:sdr" | chpasswd && adduser sdr sudo && usermod -a -G audio,dial 2.0s

[base 3/17] RUN useradd -m sdr -u 0 && echo "sdr:sdr" | chpasswd && adduser sdr sudo && usermod -a -G audio,dialout,plugdev sdr && sudo usermod --shell /bin/bash sdr: 0.765 useradd: UID 0 is not unique
