Time zone settings are missing in docker image. R returns 'no Olson database found'

[aabor]

I start docker container:

docker run -p8787:8787-e "USER=rstudio" -e "PASSWORD=123" --rm rocker/tidyverse:4.0.0-ubuntu18.04

than inside docker container I run the following RLanguage command in RStudio:

OlsonNames() character(0) Warning message: In OlsonNames() : no Olson database found

As a consequence all time dependent functions do not work, including for example read_csv from 'readr'

In docker image RStudio terminal I run:

cat /etc/timezone
Etc/UTC

Any work around?

Can you please use one of the focal based images? 4.0.0-ubuntu18.04 tag is no longer actively supported.
