The problem also occurs with epa-sign-file, which is easier to reproduce (because it doesn't need as much configuration). So I am reporting the bug for this command. To reproduce, emacs -Q, then execute in the *scratch* buffer: (write-region "hello\n" nil "hello.txt") (require 'epa) (let ((epg-pinentry-mode 'loopback) (epa-protocol 'CMS)) (epa-sign-file "hello.txt" (epa-select-keys (epg-make-context epa-protocol) "Key:" nil t) 'normal)) This asks interactively to select a key. After doing so, it fails with the following error (shown in an "*Error* (EPA Info)" buffer): Error while signing with "/usr/bin/gpgsm": gpgsm: ignoring gpg-agent inquiry 'PASSPHRASE' gpgsm: error creating signature: No passphrase given Debugger *Backtrace* (key IDs x-ed out): Debugger entered--Lisp error: (epg-error "Sign failed" "") signal(epg-error ("Sign failed" "")) epa-sign-file("hello.txt" (#s(epg-key :owner-trust nil :sub-key-list (= #s(epg-sub-key :validity nil :capability (encrypt sign) :secret-p nil :algo= rithm 1 :length 4096 :id "XXXXXXXXXXXXXXXX" :creation-time 20231107 :expira= tion-time 20251106 :fingerprint "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")= ) :user-id-list (#s(epg-user-id :validity nil :string (("CN" .

"DE"))= :signature-list nil) #s(epg-user-id :validity nil :string "" :signature-list nil)))) normal) (let ((epg-pinentry-mode 'loopback) (epa-protocol 'CMS)) (epa-sign-fil= e "hello.txt" (epa-select-keys (epg-make-context epa-protocol) "Key:" nil t= ) 'normal)) (progn (let ((epg-pinentry-mode 'loopback) (epa-protocol 'CMS)) (epa-s= ign-file "hello.txt" (epa-select-keys (epg-make-context epa-protocol) "Key:= " nil t) 'normal))) eval((progn (let ((epg-pinentry-mode 'loopback) (epa-protocol 'CMS)) (= epa-sign-file "hello.txt" (epa-select-keys (epg-make-context epa-protocol) = "Key:" nil t) 'normal))) t) elisp--eval-last-sexp(t) eval-last-sexp(t) eval-print-last-sexp(nil) funcall-interactively(eval-print-last-sexp nil) call-interactively(eval-print-last-sexp nil nil) command-execute(eval-print-last-sexp) When I change epg-pinentry-mode to ask or epa-protocol to OpenPGP in the let-binding, things work as expected. In other words, only the combination of S/MIME and pinentry loopback fails. | | OpenPGP | CMS | |----------+---------+-------| | ask | works | works | | loopback | works | fails | I use pinentry-gnome3, in case this should matter: $ readlink /usr/bin/pinentry pinentry-gnome3 In GNU Emacs 29.1 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo version 1.18.0) of 2023-10-24 built on localhost Windowing system distributor 'The X.Org Foundation', version 11.0.12101009 System Description: Gentoo Linux Configured using: 'configure --prefix=3D/usr --build=3Dx86_64-pc-linux-gnu --host=3Dx86_64-pc-linux-gnu --mandir=3D/usr/share/man --infodir=3D/usr/share/info --datadir=3D/usr/share --sysconfdir=3D/etc --localstatedir=3D/var/lib --datarootdir=3D/usr/share --disable-silent-rules --docdir=3D/usr/share/doc/emacs-29.1-r5 --htmldir=3D/usr/share/doc/emacs-29.1-r5/html --libdir=3D/usr/lib64 --program-suffix=3D-emacs-29 --includedir=3D/usr/include/emacs-29 --infodir=3D/usr/share/info/emacs-29 --localstatedir=3D/var --enable-locallisppath=3D/etc/emacs:/usr/share/emacs/site-lisp --without-compress-install --without-hesiod --without-pop --with-file-notification=3Dinotify --with-pdumper --enable-acl --with-dbus --with-modules --with-gameuser=3D:gamestat --with-libgmp --with-gpm --without-native-compilation --without-json --without-kerberos --without-kerberos5 --with-lcms2 --with-xml2 --without-mailutils --without-selinux --with-small-ja-dic --without-sqlite3 --with-gnutls --without-libsystemd --with-threads --without-tree-sitter --without-wide-int --with-sound=3Dalsa --with-zlib --with-x --without-pgtk --without-ns --without-gconf --with-gsettings --without-toolkit-scroll-bars --with-xpm --with-xft --with-cairo --with-harfbuzz --with-libotf --with-m17n-flt --with-x-toolkit=3Dlucid --with-xaw3d --with-gif --with-jpeg --with-png --with-rsvg --with-tiff --without-webp --with-imagemagick --with-dumping=3Dpdumper 'CFLAGS=3D-march=3Dnative -ggdb -O2 -pipe' 'LDFLAGS=3D-Wl,-O1 -Wl,--as-needed'' Configured features: ACL CAIRO DBUS FREETYPE GIF GLIB GMP GNUTLS GPM GSETTINGS HARFBUZZ IMAGEMAGICK JPEG LCMS2 LIBOTF LIBXML2 M17N_FLT MODULES NOTIFY INOTIFY PDUMPER PNG RSVG SECCOMP SOUND THREADS TIFF X11 XAW3D XDBE XIM XINPUT2 XPM LUCID ZLIB Important settings: value of $LC_CTYPE: en_GB.UTF-8 value of $LC_TIME: en_GB.UTF-8 value of $LANG: POSIX locale-coding-system: utf-8-unix Major mode: Lisp Interaction Minor modes in effect: tooltip-mode: t global-eldoc-mode: t eldoc-mode: t show-paren-mode: t electric-indent-mode: t mouse-wheel-mode: t tool-bar-mode: t menu-bar-mode: t file-name-shadow-mode: t global-font-lock-mode: t font-lock-mode: t blink-cursor-mode: t line-number-mode: t indent-tabs-mode: t transient-mark-mode: t auto-composition-mode: t auto-encryption-mode: t auto-compression-mode: t Load-path shadows: None found.
