It appears that the following ebuild fixes: sed -e "s|gnupg/:|:|g" -i configure.ac || die [[ -f /usr/lib/gnupg/gpgkeys_hkp ]] && myconf="--libexecdir=/usr/$(get_libdir)" stopped working at some point in the last 8 years (or never worked properly): # strings -a /usr/bin/gpa | grep libexec ${exec_prefix}/libexec/gnupg When attempting to retrieve a key from the GPA interface: $ strace gpa 2>&1 | grep keys_ access("${exec_prefix}/libexec/gnupg/gpg2keys_hkp", F_OK) = -1 ENOENT (No such file or directory) That's the only message -- probably because the fallback path (as above, but with "gpgkeys_hkp") is then attempted to be spawned in a fork (see src/server-access.c). src/server-access.c uses GPA_KEYSERVER_HELPERS_DIR, which is defined in gpadefs.h.in as KEYSERVER_HELPERS_DIR, which, according to configure.ac, is set to directory name of gpgkeys_ldap (that is searched in outdated directories, but the sed line above should probably fix that). So it seems that if app-crypt/gnupg is built with USE=-ldap, GPA will not be able to use any GnuPG helpers to retrieve and upload keys. TL;DR: gpa's configure searches for gpgkeys_ldap, and sets prefix for all helpers accordingly -- using garbage prefix and outdated suffix if it can't find the file. Using e.g., gpg2keys_hkp should probably fix that, since GPGKEYS_LDAP is apparently not directly used otherwise.
Temporarily creating /usr/libexec/gpgkeys_ldap (with mode 0755) before emerging app-crypt/gpa fixes the issue: # strings -a /usr/bin/gpa|g libexec /usr/libexec So replacing gpgkeys_ldap with e.g., gpgkeys_hkp (or gpg2keys_hkp) in configure.ac will probably work.
Thanks for reporting, fixed it.
It is not fixed: # strings -a /usr/bin/gpa | grep libexec /usr/libexec/gnupg
Moreover, the approach in comment #1 ("temporarily creating /usr/libexec/gpgkeys_ldap") doesn't work anymore, so key import in GPA is now broken for all gnupg-2 users, not just gnupg[-ldap].
A temporary workaround, if anyone needs one: ln -s . /usr/libexec/gnupg
please re-emerge gpa-0.9.3
Thanks, seems to be fixed: # strings /usr/bin/gpa | grep libexec /usr/libexec
