This is happening because your local copy of ~/dlang/d-keyring.gpg is out of date with the dlang.org server.
To fix, the install.sh script should fetch the latest version of https://dlang.org/d-keyring.gpg periodically.
As a workaround remove `~/dlang/d-keyring.gpg` and try again.

I think the install script should tell the user about this workaround.
