[Copilot]

This curl removal appears unnecessary since curl is not explicitly installed in the final image stage. Looking at line 37, curl is not included in the clean-install package list. Curl was only installed in the builder stage (line 24), which is discarded during the multi-stage build. Unless curl is being pulled in as a transitive dependency of packages on line 37, this command serves no purpose. Please verify whether curl is actually present in the final image. If it is not present, remove this line. If curl is indeed present as a dependency and needs to be removed, consider combining this with line 37 using && to reduce image layers, following Docker best practices.

Suggested change

RUN apt remove curl -y
