• SqlPackage or DacFx Version: 162.0.52.1
• .NET Framework (Windows-only) or .NET Core: 1.1.0
• Environment (local platform and source/target platforms): ubuntu 20.04

Steps to Reproduce:
In my team, we want to import an exported bacpac from azure sql to local machine. Then we use the official sql server for linux image and sql package to restore the database.

Our bacpac file use the collcation with Chinese_PRC_CI_AS, whose LCID is 2052

We use the following to build a custom image.

FROM mcr.microsoft.com/mssql/server
USER root
VOLUME download
RUN apt-get update \
    && ACCEPT_EULA=Y apt-get install -y \
        unzip \
        msodbcsql18 \
        mssql-tools18 \
        libunwind8 \
        libicu-dev
RUN wget --no-check-certificate -O sqlpackage.zip https://download.microsoft.com/download/9/1/6/9167b423-2087-4210-93ec-c9467a408ea2/sqlpackage-linux-x64-zh-Hans-162.0.52.1.zip 
  && unzip -q sqlpackage.zip -d /opt/sqlpackage || true
  && chmod +x /opt/sqlpackage/sqlpackage 
  && rm /sqlpackage.zip
#USER mssql
ENV PATH=$PATH:/opt/mssql-tools/bin:/opt/sqlpackage

And we use the following commands to initiate the container and import the bacpac file.

docker run -d -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=Admin12345-' -e "MSSQL_COLLATION=Chinese_PRC_CI_AS" -e "MSSQL_LCID=2052" -p 1433:1433 --name sqlfts0 db-test
docker exec -it sqlfts0 /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P 'Admin12345-' -Q 'CREATE DATABASE MyDb0'
docker cp ~/Downloads/database.bacpac sqlfts0:/download/database.bacpac
docker exec -it sqlfts0 /opt/sqlpackage/sqlpackage /A:Import /tsn:localhost /tu:SA /tp:'Admin12345-' /tdn:MyDb0 /sf:/download/database.bacpac /TargetEncryptConnection:False /TargetTrustServerCertificate:True

However, the import failed.

Importing to database 'MyDb1' on server 'localhost'.
