I managed to get things back to normal, perhaps this can help (at least
someone).
In .gnupg/gpg-agent.conf I went from "pinentry-program pinentry-qt" to
"pinentry-program pinentry". After each edition of that file, I did
`killall gpg-agent`, and to test (from Enigmail troubleshooting doc) :
gpg-connect-agent <<EOT
GET_CONFIRMATION Hello
EOT
When "pinentry-program" set to "pinentry-qt" (with or without the full
path), I get the error "ERR 67108949 No pinentry <GPG Agent>". However,
with other tests, such as:
pinentry-qt <<EOT
SETDESC Hello World
CONFIRM
EOT
I can see the QT Pinentry prompt.
I have to either comment out "pinentry-program" or set it to "pinentry"
and everything is back to "normal".
I'm not sure where to go from here, for now, I can at least read emails
as usual.
Cheers,
