This seems to be a problem peculiar to Catalina (macOS 10.15.1). There is a
fix, as Otared and Glen have indicated.

go to Apple menu -> Preferences -> Security & Privacy
on the Security & Privacy, login, choose the tab General
there choose, towards the bottom of that pane, under « Allow apps
downloaded from: »
                   choose the radio button App Store and identified
developers
                   click the button «allow anyway»

The macOS still chokes when you first try to update lmtx , but this time it
presents the option «Open». Select that and you are good to go.

So, thanks, guys.

And Mojca, yes, it is very confusing. Still, that seems to be all that one
has to do make the download. So perhaps there is no need for changes at
your end.

Cheers, Alan
