Hash Sum mismatch failures

[jamshid]

Does anybody else get "Hash Sum mismatch" errors when using this proxy? Restarting the aptcacherng container doesn't seem to help. Even deleting its data volume (it reached 1.4GB) and restarting the container does not fix it. Nor does docker system prune -f --volumes to clear docker image build layers. The docker server is 19.03.11 and ubuntu 16, but upgrading docker to 19.03.13 didn't help.

Finally the fix seemed to be adding apt-get clean && rm -rf /var/lib/apt/lists/* && apt-get update && to the beginning of every RUN command in my Dockerfile which used apt-get. Hopefully this helps someone.

[bucky2076]

yes I am getting similar errors.
I also get tcp/ip address problems randomly occur. When it fails I simply re-start the job. Sometimes have to do this several times before it works.
thanks for your fix.
I suspect need some kind of timeout parameter in case the container cannot respond quickly enough to the request from the client.

[bucky2076]

errors with this container are escalating... getting hash sum mismatch, and tcp closed connection errors.
I've capitulated, and moved acng to a virtual machine. Works great now.

[jamshid]

Hmm @sameersbn do you happen to know what might be causing these errors? Now I'm paranoid about SolarWinds / Sunburst build system hacking.

[bucky2076]

with container, I could not easily get access to the acng.conf file. Perhaps the standard install needs tweaking, but would want the conf file to maintain state after upgrading.

FWIW I switched my image to mbentley/apt-cacher-ng (https://github.com/mbentley/docker-apt-cacher-ng) and I don't seem to be seeing the weird Hash Sum mismatch errors anymore.

services:
  aptcacherng:
    deploy:
      resources:
        limits:
          memory: 300m
    image: mbentley/apt-cacher-ng
    init: true
    ports:
    - published: 3142
      target: 3142
    restart: always
    volumes:
    - aptcacherng:/var/cache/apt-cacher-ng:rw
volumes:
  aptcacherng: {}

@bucky2076 's solution is the way to go: run a dedicated VM for that.

I tried everything, from this image, the other named image and creating my own based on recent Debian. Nothing solved the "Hash sum missmatch".

Running in a VM will help, but you have to double check with the underlying filesystem. I was using 9P first to use NAS's storage, but it resulted in the same "has sum missmatch" errors then before.. at least it took longer/bigger files.

You can go with a filesystem on the VM itself. I was successful using CIFS with the following options:

 noserverino,credentials=xxxxx,uid=102,gid=110,dir_mode=0755,file_mode=0755
