[pkg-gnupg-maint] Bug#950836: gpg-agent: generator 90gpg-agent and user with no home crontask generate annoying logs

[lwafflard]

Package: gpg-agent
Version: 2.2.12-1+deb10u1
Severity: normal

Dear Maintainer,

Every day I receive some logs after cron.daily execution like these

	systemd[2626]: gpgconf: running /usr/bin/gpg-agent failed (exitcode=2): General error
	systemd[2626]: gpgconf: fatal error (exit status 1)

Some cron tasks are executed as «nobody» user, which have no home. When executing the script «/usr/lib/systemd/user-environment-generators/90gpg-agent» as nobody, gpgconf break with these lines. To reproduce, you can also as root

	sudo -u nobody gpgconf --list-options gpg-agent

Is it possible to update the user-environment-generator ? Redirect stderr would be sufficient ?

	if [ -n "$(gpgconf --list-options gpg-agent | \
=>
	if [ -n "$(gpgconf --list-options gpg-agent 2>/dev/null | \

Masking globally all gpg services/socket as suggested in /usr/share/doc/gpg-agent/README.Debian is ineffective as generator executed on each new session.

Regards,
L.Wafflard
