I have a Linux AWS machine and i started having this issue a few days ago:

Err http://deb.debian.org jessie-updates/main amd64 Packages


Err http://deb.debian.org jessie-updates/main amd64 Packages


Err http://deb.debian.org jessie-updates/main amd64 Packages
  404  Not Found

W: Failed to fetch http://deb.debian.org/debian/dists/jessie-updates/main/binary-amd64/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.
Exited with code 100

my CircleCI config.yml errors out here (on install aweswebsli):

- run:
      name: Install awsebcli
      working_directory: ~/
      command: |
        sudo apt-get update
        sudo apt-get install python-dev python-pip
        sudo easy_install --upgrade six
        sudo pip install urllib3==1.21.1
        sudo pip install awsebcli==3.14.11

some solution suggest modifying

/etc/apt/resources.list

but i can't find this folder/file on my AWS Linux.

Other posts suggest replacing this line

sudo apt-get update

with

apt-get -o Acquire::Check-Valid-Until=false update

without success. Any help is appreciated.
