Redis – R installation in Docker gets stuck in Geographic area

I am installing R in docker using the following statement.

RUN apt-get update 
    && apt-get install -y --no-install-recommends 
        littler 
        r-cran-littler 
        r-base 
        r-base-dev 
        r-recommended 
        && echo 'options(repos = c(CRAN = "https://cloud.r-project.org/"), download.file.method = "libcurl")' >> /etc/R/Rprofile.site 
        && echo 'source("/etc/R/Rprofile.site")' >> /etc/littler.r 
    && ln -s /usr/share/doc/littler/examples/install.r /usr/local/bin/install.r 
    && ln -s /usr/share/doc/littler/examples/install2.r /usr/local/bin/install2.r 
    && ln -s /usr/share/doc/littler/examples/installGithub.r /usr/local/bin/installGithub.r 
    && ln -s /usr/share/doc/littler/examples/testInstalled.r /usr/local/bin/testInstalled.r 
    && install.r docopt 
    && rm -rf /tmp/downloaded_packages/ /tmp/*.rds 
    && rm -rf /var/lib/apt/lists/*

It ask a set of questions. In the first of all it gets stuck and I don’t know why:

Configuring tzdata
------------------

Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.

  1. Africa      4. Australia  7. Atlantic  10. Pacific  13. Etc
  2. America     5. Arctic     8. Europe    11. SystemV
  3. Antarctica  6. Asia       9. Indian    12. US

I answerthe following but nothing happens:

Geographic area: 8
