I am building a Docker image based on debian:buster-slim
and installing cUrl in this image. According to the recommendations made by Hadolint, I install all packages via apt-get
with the option --no-install-recommends
to avoid the installation of unneeded packages.
Installed in this way, cUrl is not able to get any file via HTTPS due to it is unable to find the "local issues certificate", as shown in the extract from Docker output below.
Does someone know which additional package I have to install to solve this problem?

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and

This is my current version of the use Dockerfile:
