logrotate, cron and gpg
lists at merit.unu.edu

We are trying to encrypt log files via logrotate & cron, and I hope
someone here can help out a bit.
Our logrotate configuration file contains:
> olddir gpg/
> compresscmd /usr/bin/gpg
> compressoptions -vv --verbose --encrypt --default-key A4DB7xxxD98
> compressext .gpg
Now, when logrotates runs the above from cron, we're getting:
> gpg: cannot open '/dev/tty': No such device or address
> error: failed to compress log /logrotate/gpg//test.log.1
We know --no-tty exists, but it doesn't help in this case, because when
> gpg: Sorry, no terminal at all requested - can't get input
I do see various howto's that use gpg to encrypt their logfiles this
way, for example: https://www.ctrl.blog/entry/gdpr-web-server-logs.html
So, we're asking the experts here: What could be our issue, and how to
make this work..?
This is on debian 10.9
Thanks for any pointers!
