      There seems to be a way around this built into Catalina, however
      awkward it may be.

      <div>I tried to install lmtx on a computer running
        Catalina that didn’t have an installation and received a similar
        error. (There seems to be a quarantine applying to the text of
        the script and not merely the file because I tried creating a
        new document with the same text and received the same response,
        and that response referred to the download of the original
        file.)</div>
      <div><br>
      </div>
      <div>I did find that the “general” tab under “security
        & privacy” in the system preferences had, in addition to the
        usual two choices, a reference to the downloaded script with a
        button reading “allow anyway” (or something to that effect).
        When I tried to run the script again after clicking that button,
        the “developer cannot  be verified” dialogue included “open” as
        a choice; and, when I clicked that, the script ran successfully
        and the installation was usable.</div>
      <div><br>
      </div>
      <div>I then tried the install script on another computer
        running Cataline where I had installed lmtx last spring. I ran
        into the “developer cannot be verified” response again, but the
        same workaround allowed the script to run, and the installation
        was updated.</div>
