You can solve it by using the below line

RUN dotnet restore --disable-parallel

Worked for me. In addition, instead of disabling parallelism at all, setting 5 'maxHttpRequestsPerSource' in NuGet.config improve performances, and still should work. – Formalist Jun 08 '22 at 20:34

Worked for me too. I am on a super slow connection in remote part of Greece and this got it to pass. Thank you! – D3vtr0n Aug 08 '22 at 18:49

I had the same error, I tried this and it worked.

Stop all the running containers docker stop $(docker ps -aq)
Delete all the containers docker rm $(docker ps -aq) which are stopped by the previous commands.
Delete all the volumes by using docker volume rm $(docker volume ls -q)
Better to clean up all old docker images by using docker rmi -f $(docker images -a -q)
Or you could purge all the data by using Docker Desktop UI.
Then you could go to the src directory and build all the images again using docker-compose build and then followed by docker-compose up

!IMPORTANT Please note, the above commands will clean up all the docker related instances on that environment. So it's not recommended to run these on any production environment or any other environment where docker instances of any other applications are running.

I replaced this

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base

on this

FROM microsoft/aspnetcore-build:2.0.0 AS build

and after that replaced this

FROM mcr.microsoft.com/dotnet/core/sdk:3.1

on this

FROM microsoft/aspnetcore:2.0.0

In my .csproj file replecad version of netcoreapp from 3.1 to 2.0. As I understood problems were in versions of docker images.
