    apt-get upgrade -y && \
    apt-get install -y  software-properties-common \
    apt-utils \
    libxml2-dev \
    openjdk-8-jdk \
    build-essential \
    libcurl4-gnutls-dev \
    libssl-dev \
    openssh-server && \
    apt-get clean

您的最终dockerfile将是：

FROM rocker/r-ubuntu:20.04

LABEL maintainer="Utkarsh Saraf"

ARG DEBIAN_FRONTEND=noninteractive

RUN apt-get update && \
    apt-get upgrade -y && \
    apt-get install -y  software-properties-common \
    apt-utils \
    libxml2-dev \
    openjdk-8-jdk \
    build-essential \
    libcurl4-gnutls-dev \
    libssl-dev \
    openssh-server && \
    apt-get clean


# for enabling SSh in container                #
EXPOSE 80 2222 3306 8081

WORKDIR /app
COPY . /app
COPY start.sh start.sh
ENTRYPOINT ["sh", "/app/startup.sh"]

我希望这一部分能帮助你解决你的问题
