git suddenly started putting up a dialog instead of asking for my password on the command line

[Joel Rees]

Okay, let's try this question:

Does anyone know whether current (Ubuntu 18.04) versions of ssh, gnupg, or git
have recently taken to putting up a modal dialog box for your
authentication tokens
when invoked by a git push from the command line?

Or, as an option, whether one of the popular wallet apps (kwallet, et.
al.) might
be doing something to insert such a modal dialog into your chain of agents
even when invoked by a git push on the command line?
