I have configured mysql-zrm and I am trying to launch mysql-zrm-scheduler with the account called "mysql" because I do not want to use "root".

When launching as presented below:
mysql-zrm-scheduler --now --backup-set dailyrun --backup-level 0

I get the below error:
dailyrun:backup:ERROR: backup failed
dailyrun:backup:ERROR: Output of command: 'compress/encrypt' is {
Passphrase file /etc/mysql-zrm/.passphrase not found at /usr/share/mysql-zrm/plugins/encrypt.pl line 80.

I have configured the passphrase; ok, I do not know WHY I have to configure it, but I do it to try to launch backups; anyway, I do not find why it does not work.

I have also tried with root account and it does not work either.

Thanks for your help and time.
