How to get "Enter passphrase" on command line rather than GUI pop-up?

[Chris Green]

Setting SSH_ASKPASS_REQUIRE=never in the environment on my xubuntu
23.10 system doesn't seem to work.  I have set it:-

    chris$ env | grep SSH
    SSH_AUTH_SOCK=/run/user/1000/keyring/ssh
    SSH_ASKPASS_REQUIRE=never
    chris$ 

But I still get the annoying GUI pop-up rather than being asked for
the passphrase in the terminal window.  Is this a bug or am I doing
something wrong?
