Resolved ERR [panel] Get dump - FTP dump file does not exists

[SKDamon]

I'm running Plesk 17.5 on Ubuntu 16.04, from my panel.log:

[2017-08-02 08:08:58] ERR [panel] Get dump 'backup_info_1707312309.xml':

In pmmcli.log:

I've fonud this workaround:
Backup Manager stopped working right after Upgrade to Plesk Onyx: Unable to get dump list

But that only supports Ubuntu 12.04. The root cause seems to be panel.ini, but I've never done manual edits on that file, in fact I can't even find panel.ini:

'/usr/local/psa/admin/conf/panel.ini': No such file or directory
'/opt/psa/admin/conf/panel.ini': No such file or directory

Both directories have a panel.ini.sampe file, so I assume I'm just running on defaults?

Anyway, how can I fix the backup process? AFAIK my customers don't even use Remote Backups to FTP...

There is only sample of panel.ini:

/usr/local/psa/admin/conf/panel.ini.sample

Just create your panel.ini from this sample and edit it:

# mv /usr/local/psa/admin/conf/panel.ini.sample /usr/local/psa/admin/conf/panel.ini

I did that and restarted plesk (BTW are there systemd units for plesk?)
The /opt path was shown by Panel.ini editor extension, that directory is just symlinked to the /usr dir.

I'm not sure what triggers the error, though, so I can't tell if that fixed it right now. I usually get the error every morning @ 8am.

Try to create backup of file /usr/local/psa/PMM/tasks/tasks.db and then remove it. This file will be recreated when you open Backup Manager in Plesk.
I hope it will help.

Fixed.
I get no more errors about Backup in the logs. I can't say for sure, but I think it was the panel.ini file which was missing, causing the errors.
But I also deleted the tasks.db just to be sure.

Thanks for the great help @IgorG!
