Support terminal-based pinentry programs. Suspend vaxis before running the command that can trigger a pinentry call. Provide the proper tty in the GPG_TTY environment variable (and set a TERM variable if not provided; this is necessary for pinentry-curses). Finally, resume vaxis. To enable terminal-based pinentry support, you have to set [general] use-terminal-pinentry = true in your aerc.conf. Any GUI-based pinentry programs will work the same as before if this option is not set to true. To test pinentry-tty, add the following to your ~/.gnupg/gpg-agent.conf: pinentry-program /usr/bin/pinentry-tty and kill all running gpg-agents: $ killall gpg-agent Fixes: https://todo.sr.ht/~rjarry/aerc/202 Changelog-fixed: Terminal-based pinentry programs (e.g. `pinentry-curses`) now work properly.

You need to set GPG_TTY manually before starting aerc. Add the following to your
|
|
.bashrc or whatever initialization file is used for shell invocations:
|
|
|
|
GPG_TTY=$(tty)
|
|
export GPG_TTY
|
|
