Not working in Linux PowerShell with `Register-PSRepository` on a Ubuntu docker image

How is this supposed to work in a Linux docker container with Register-PSRepository / Register-PackageSource? I seem to be having the same issue that's described here where these commands fail due to a missing file (possibly nuget.exe)

I'm setting this up in my docker file like so:


FROM ubuntu:22.04

RUN wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb && dpkg -i packages-microsoft-prod.deb

RUN apt-get update && apt-get install -y --no-install-recommends \         
  curl jq git gnupg zip unzip iputils-ping libcurl4 libunwind8 netcat libssl1.0 openssh-client \
  lxc iptables apt-transport-https powershell software-properties-common dotnet-sdk-8.0\
  && apt autoremove -y \
  && rm -rf /var/lib/apt/lists/*  

ARG ADO_USER="user@company.com"
ARG ADO_TOKEN="somevalidtoken"
ARG ADO_SOURCE="PSNuGet"
ARG ADO_URL="https://pkgs.dev.azure.com/company/_packaging/${ADO_SOURCE}/nuget/v2"

ENV NUGET_CREDENTIALPROVIDER_SESSIONTOKENCACHE_ENABLED="True"
ENV VSS_NUGET_EXTERNAL_FEED_ENDPOINTS="{\"endpointCredentials\": [{\"endpoint\":\"${ADO_URL}\", \"username\":\"${ADO_USER}\", \"password\":\"${ADO_TOKEN}\"}]}"

RUN curl -L https://raw.githubusercontent.com/Microsoft/artifacts-credprovider/master/helpers/installcredprovider.sh  | sh
ENV PATH="${PATH}:/root/.nuget/plugins/netcore/CredentialProvider.Microsoft"

But when I run the Register-PSRepository command I get these errors

Register-PSRepository `
    -Name "PSNuGet" `
    -SourceLocation "https://pkgs.dev.azure.com/company/_packaging/PSNuGet/nuget/v2" `
    -PublishLocation "https://pkgs.dev.azure.com/company/_packaging/PSNuGet/nuget/v2" `
    -InstallationPolicy Trusted

The plugin does seem to work by itself in that its able to find the credentials with this command

dotnet ~/.nuget/plugins/netcore/CredentialProvider.Microsoft/CredentialProvider.Microsoft.dll -Uri "https://pkgs.dev.azure.com/company/_packaging/PSNuGet/nuget/v2" -Verbosity Debug

If I register the package source and then attempt to install a module I get similar errors

What am I missing here?
