shiny docker 映像构建因 ubuntu ZEFE90A8E604A7C840E88D03A67F6Z 问题而失败

Question

我正在尝试为我的 R shiny 应用程序构建 docker 图像。 下面是Dockerfile 。

# Install R version 3.6
FROM r-base:3.6.0

# Install Ubuntu packages
RUN apt-get update && apt-get install -y \
    sudo \
    gdebi-core \
    pandoc \
    pandoc-citeproc \
    libcurl4-gnutls-dev \
    libcairo2-dev \
    libxt-dev \
    xtail \
    wget \
    libudunits2-dev \
    libgdal-dev

# Install R packages that are required
RUN R -e "install.packages(c('remotes', 'tidyr', 'dplyr', 'ggplot2', 'stringr','shiny', 'shinydashboard','shinyWidgets','shinyjs', 'rlang','scales','DT','lubridate', 'plotly',  'leaflet', 'leafpop', 'visNetwork', 'wordcloud2', 'arules'), repos='http://cran.rstudio.com/')"
RUN R -e "remotes::install_github('nik01010/dashboardthemes')"

# Download and install ShinyServer (latest version)
RUN wget --no-verbose https://download3.rstudio.org/ubuntu-14.04/x86_64/VERSION -O "version.txt" && \
    VERSION=$(cat version.txt)  && \
    wget --no-verbose "https://download3.rstudio.org/ubuntu-14.04/x86_64/shiny-server-$VERSION-amd64.deb" -O ss-latest.deb && \
    gdebi -n ss-latest.deb && \
    rm -f version.txt ss-latest.deb

# Copy configuration files into the Docker image
COPY shiny-server.conf  /etc/shiny-server/shiny-server.conf
COPY /app /srv/shiny-server/

# Make the ShinyApp available at port 80
EXPOSE 80

# Copy further configuration files into the Docker image
COPY shiny-server.sh /usr/bin/shiny-server.sh

CMD ["/usr/bin/shiny-server.sh"]

然而，我的形象建设很早就失败了。 以下是所有日志。 似乎有些 Ubuntu package 问题我不太明白。

我是 docker 的新手。 我不知道如何处理这些错误消息。 感谢是否有人可以帮助找出需要做的事情。 谢谢。

您收到的错误消息不是 Docker 特定的，而是与您的 package manager apt相关。

尽管您正在使用apt-get update package 列表，但您不会安装更新版本的软件包。 现在发生的情况是您正在尝试安装已安装的 package 的较新版本，这会导致错误消息。

如果您使用apt-get upgrade ， apt将安装已安装软件包的较新版本。

如下所示更改第 5 行将解决该问题：

RUN apt-get update && apt-get upgrade -y && apt-get install -y \
