Docker Desktop on mac OS Big Sur 11.1 makes error on “RUN apt-get -y update”

[rmenoli]

I have the following problem: If I try to build an image from this dockerfile:

FROM python:3.7
RUN apt update

I'm building it with the following command: docker build -t myimage got the following error:

executor failed running [/bin/sh -c apt update]: exit code: 100I got the following error:

I'm working on MAC OS Big Sur 11.1 If I do the same command on an Ubuntu machine on AWS with the same Dockerfile and it worked!

I get the same error even with the following Dockerfile:

FROM ubuntu:18.04

RUN apt-get update

I tried to uninstall and reinstall docker desktop but nothing changed.. I have Docker 3.0.3

What is the problem?

[stephen-turner]

It looks to me like the error is in the Debian package repository not in any Docker code.

[DanyHenriquez]

It does work on Catalina and before. When browsing the page from the Macbook itself it also doesn't allow the page to be displayed on Big Sur but it does on Catalina.

This all points to a combination of the package repo and Big Sur

I have this problem after update to 11.2.3 Big Sur, any advice please?

Had the very same issue. Turned out that ScreenTime was blocking the debian URLs.

To solve the issue you need to visit all URLs that show with "failed to fetch" in your error log, e.g.

http://deb.debian.org/debian/dists/buster/main/binary-amd64/by-hash/SHA256/c88216232d353afbc95e57a5ad04fc515335fb75659dbcae6967cd1109b7e4fb

and click on "Add to list".

Found a hint here: https://stackoverflow.com/questions/62185692/docker-apt-update-some-index-files-failed-to-download-they-have-been-ignored

[ahmedalawady]

Thank you @fraukesch it's working
