solved with this:

sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/3bf863cc.pub

sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64/7fa2af80.pub

  • Where did you find those URLs? – DrMcCleod Aug 09 '23 at 14:49
  • If your base image is ubuntu 18 then adding these two as RUN statements before your apt-get update solves the issues. Very handy with tensorflow official docker image build to fix the issues. – Gautam Sep 04 '23 at 06:36
