Can't install additional software

[Jagget]

Using it as GitLab CI image. Need PIP3 library for deployment

image: alekzonder/puppeteer:latest

services:
  - docker:dind

Getting an error:

$ apt-get install python3-pip -y
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

This is probably because of rm -rf /var/lib/apt/lists/* at

docker-puppeteer/Dockerfile

Line 12 in 35983d4

apt-get clean && apt-get autoremove -y && rm -rf /var/lib/apt/lists/*
