python3.*-minimal Error during pip installation in docker build – PermissionError – using VScode

This happens with 20.04 & 22.04 docker images with python3.8-minimal and python3.10-minimal (respectively, these are the only ones I’ve tried). Images are being built within VScode.
The problem occurs during

apt install pip

output:

I have tried building a container with nothing in it and running the commands from inside the container.

sudo apt install pip

and

sudo apt install python3-pip

still fail

The output is then:

        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en_US.UTF-8"

This doesn’t seem to be reproducible on other PCs

failing minimal Dockerfile:

FROM ubuntu:20.04

RUN apt update -y && apt upgrade -y

RUN apt install pip -y

Any help would be greatly appreciated
