Hi J.P.

Thanks for taking the time.

It sounds like you've successfully reproduced it, because it's attempted to decrypt the auth-source file.

Now I feel like I'm definitely missing something. Why does it do this? I assume nothing in this file is required to connect to irc.libera.chat, since the connection succeeds if the file is not present.

I've had the prompt from gnome keyring on Ubuntu (I assume that's what it is) and gtk-pinentry on another machine. But my issue is that the prompt occurs at all.

yes it is blank.

Thanks

I haven't tried very hard to reproduce this yet, but I can't seem to get
Emacs to prompt me from emacs -Q. It just decrypts the file straight
away if it has access to the key it was encrypted with and fails
otherwise. So, I was wondering if this prompt is coming from somewhere
external, such as a secrets manager or a TTY pinentry program, for
example,

Please enter the passphrase to unlock the OpenPGP secret key:

(although, from your description, it seems like you're using graphical
Emacs). Also, is the "irc.libera.chat:6697" buffer completely blank
after the failure? And is there anything relevant recorded in the
"*Messages*" buffer? Perhaps something like:

For information about GNU Emacs and the GNU system, type C-h C-a.
Decrypting /root/.authinfo.gpg...done
epa-file-insert-file-contents:
Opening input file: Decryption failed, , No secret key

I'm mainly trying to avoid having to replicate your setup in a VM.

TIA,
J.P.
