@mthalman @MichaelSimons I am wondering if you can help me on this issue. I keep getting the following when trying to update the docker image. And I cannot find anywhere setlocale is used in install script

/usr/bin/sh setlocale: LC_ALL: cannot change locale (en_US.UTF-8) [/home/vsts/work/1/s/.nuget/packages/microsoft.dotnet.arcade.sdk/1.0.0-beta.19474.3/tools/Tools.proj]

@wli3 - according to this post, the LANG is misspelled.

Your locale should be en_US.utf8 not en-US.UTF-8

[wli3]

I changed the docker file to ENV LANG=en_US.utf8 it still won't work.
With the same error message "cannot change locale (en_US.UTF-8)". I don't know what is trying to set en_US.UTF-8

I also find many similar problem like https://github.com/dotnet/coreclr/issues/22823 dotnet/corefx#34385 but still don't know the cause other than "it is a docker authoring issue". Do you know what caused it?

[MichaelSimons]

Digging a little bit I found this suggestion: https://stackoverflow.com/a/55255020/3182557. It is not the prettiest solution but it seems to work for the experiment I tried.

[wli3]

still won't work :(

@mthalman I find the tag on

https://github.com/dotnet/versions/blob/master/build-info/docker/image-info.dotnet-dotnet-buildtools-prereqs-docker-master.json

But i get

Step 1/13 : FROM microsoft/dotnet-buildtools-prereqs:alpine-3.9-helix-2e197e0-20190918214006
manifest for microsoft/dotnet-buildtools-prereqs:alpine-3.9-helix-2e197e0-20190918214006 not found: manifest unknown: manifest unknown
##[error]Bash exited with code '1'.

At the same time, I just trying out different image blindly. A different 3.9 (microsoft/dotnet-buildtools-prereqs:alpine-3.9-helix-af66924-20190215231918) image give me the following, meaning I cannot even run a Arcade restore. Is there any image in used by any Arcade supported build?

It's because you're referencing the old repository on Docker Hub that we don't publish to any longer. You should reference it as mcr.microsoft.com/dotnet-buildtools/prereqs:alpine-3.9-helix-2e197e0-20190918214006.

@dotnet/dotnet-cli mostly just remove old docker files and removing out dated distro legs

[nguerrera]

How many legs does this remove? Can we target it at 3.0?

[wli3]

@nguerrera it removes 5 legs. And I would port it to 3.0. However I am seeing flaky error like dotnet/dotnet-buildtools-prereqs-docker#199 I did some change. But I am not sure the problem is fixed. Now rerun more times to be sure

[wli3]

No more Debian Stretch error. I will merge it once tests passed
