Cross posted from r/Docker:

I have 2 dev environments, WSL and Ubuntu Linux. I have a custom Dockerfile for Postgres that installs TimescaleDB for me. For whatever reason, the container runs perfectly fine in Ubuntu but is giving me the following errors in WSL:

The files belonging to this database system will be owned by user "postgres". This user must also own the server process. initdb: error: invalid locale settings; check LANG and LC_* environment variables

Dockerfile: ``` FROM postgres:${POSTGRES_VERSION} ARG TIMESCALE_VERSION ARG POSTGRES_VERSION ENV LC_COLLATE=en_US.UTF-8 ENV LC_CTYPE=en_US.UTF-8

Can anyone help me figure out what's going on?
