ERROR: Your kernel version indicates a revision number of 255 or greater. Glibc has a number of built in assumptions that this revision number is less than 255.

Hi, my docker image was able to build last week but it fails to build with this error today using the same Dockerfile. I am not really sure how to fix it. Should a specific version of any of the packages be installed?

FROM public.ecr.aws/ubuntu/ubuntu:20.04_stable as build-image

  apt-get install -y \
  g++ \
  make \
  cmake \

This has now been fixed in the Ubuntu base image https://bugs.launchpad.net/ubuntu/focal/+source/glibc/+bug/1962225 It was caused by a no-longer-needed check when installing glibc.
