GPG doesn't work in crontab

/usr/bin/gpg --no-tty --passphrase-file /home/vouuuuuuuuu/settings/passfile.txt --decrypt-files /home/juhuuu/dirname/*.gpg;

• works fine now thank to --no-tty
• before in cron job log gpg: cannot open/dev/tty': No such device or address`
• so it could not execute before, now is fine!

Add -vv to the gpg command to see more output. It might have to do with a missing ~/.gnupg though.

To resolve this problem just add the "--no-tty" option to your gpg command line. answer was taken from a cached google page
