Public bug reported: Postfix package doesn't utilize update-ca-certificate's hooks mechanism. By simply copying certs from /etc/ssl/certs/ca-certificates.crt to /var/spool/postfix/etc/ssl/certs/ca-certificates.crt, this warning and potential security issues could be avoided.
Something like this would be a start: $ cat /etc/ca-certificates/update.d/postfix #!/bin/bash if [ -e /var/spool/postfix/etc/ssl/certs/ca-certificates.crt ]; then echo "Updating postfix chrooted certs" cp /etc/ssl/certs/ca-certificates.crt /var/spool/postfix/etc/ssl/certs/ca-certificates.crt systemctl reload postfix fi ** Affects: postfix (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915238 Title: warning: /var/spool/postfix/etc/ssl/certs/ca-certificates.crt and /etc/ssl/certs/ca-certificates.crt differ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1915238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
