signature error when installing DMD on linux

[J.R. Allen via Digitalmars-d]

I am trying to get the latest version of DMD installed on my 
computer, which is running the latest version of Linux Mint.  I 
used the install script shown on the DMD download page, which is

"curl -fsS https://dlang.org/install.sh | bash -s dmd"

but when this runs, it errors out with the following message:

Is the signature file on the server out of date?
