Previous arm64 solutions build stop working

[valeria-tejada-incontact]

Describe the Bug

On our current solutions, we use dotnet build for arm64 architecture using sdk:3.1.402-bionic-arm64v8 image, this used to work properly until December 20th, after that date we experienced a return code 1.

Steps to Reproduce

1. Create a base solution using netcore 3.1
2. Add docker support
3. Insert the following docker code: `FROM mcr.microsoft.com/dotnet/core/runtime:3.1.8-bionic-arm64v8 AS base WORKDIR /app EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1.402-bionic-arm64v8 AS devBase WORKDIR /src

FROM devBase AS build COPY . . RUN dotnet build "src/Test.sln" -c Release -o /app

FROM build AS publish RUN dotnet publish "src/Test.csproj" -c Release -o /app

FROM base AS final WORKDIR /app COPY --from=publish /app . ENTRYPOINT ["dotnet", "Test.dll"]`

4. Run docker command => docker build -f ./Dockerfile -t test .

Other Information

Usually execute this command take a few minutes but with the issue, it gets stuck around 30 min.

Output of docker version

Docker version 19.03.13, build 4484c46d9d

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

Marking for team triage. Not sure who should look into this, it sounds like a build hang on ARM64.

@tommcdon is there someone available with an arm64 machine who can do an initial look for us?

[tommcdon]

@hoyosjs can point you to a machine, and might be able to help repo

@marcpopMSFT I've sent you the credentials. However I couldn't repro the issue:

@valeria-tejada-incontact, quick questions that might help us find a way to narrow this:

• Where are you running the build? Is it a linux-arm64 machine you own? What OS is it using?
• Do you have just the source and the dockerfile in the folder, given you execute COPY . .?
• Does it reproduce every time you run the build, or is it a sporadic failure.
