          Issue ID: 21541
           Summary: ssl certificate for dlang.org
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: dlang.org
          Assignee: nobody@puremagic.com
          Reporter: pierrick.bouvier@posteo.net

On debian stable (buster - updated), it is not possible to install D from script install.sh. Even if you download this script, you will find issue since it uses curl itself.

Maybe a certificate renewal is needed.

Reproduce using (same with debian:sid)

docker run --rm=true debian:buster sh -c "apt update && apt install -y curl &&
curl https://dlang.org/install.sh"
...
curl: (60) SSL certificate problem: unable to get local issuer certificate
