No - how do you do that ?  I am just a user nunky-dunk.

Not specifically before doing the clean install of 1604. I didn't know I
had to. I backed up all my home directory and saved a few other things
that occurred to me but nothing specifically for gnupg (except the old
.gnupg in the home directory).

I copied into the .gnupg directory of the new installation the files
that I have copied over onto other machines in the past : pubring,
secring,trustdb, and conf files.

The screen output was just what gpg (1.4.20) displayed. After I solved
the missing scdaemon issue, gpg2 (2.1.11) produces the same output.

There doesn't appear to be anything wrong with the encrypted file
because it decrypts fine (as I noted) using my pre-smartcard secring.

It looks like I got the process of moving to a new installation wrong.
So I am in need of a precise process description to start again and do
it correctly.
