I found that this is a known and recurring issue with Apache binary packages. Since I can't afford to have a hosting issue stop my builds, I decided to remove the reference to this repository before I run any package updates during the build process:
# remove reference to missing repoRUN rm /etc/apt/sources.list.d/apache-arrow.sources# install dependenciesRUN apt-get update \&& apt-get upgrade -y \&& apt-get install -y \ build-essential \....I find that the build completes successfully and my service runs on the new images. Maybe there's a smarter way to do this, but this works for me.
