Resolved PleskPMMResponseException - PMMConnector.php 831

[rammstein]

Hi!

Backup-Manager (Server & Domain-Level) suddenly stopped working for me...

This did not work for me: https://kb.plesk.com/en/129828

Could this be related to: 12.5.30 Update 52 -> Plesk Migrator 2.1.10 (Microupdate, maybe a bug?)?
https://docs.plesk.com/release-notes/12.5/change-log/#12530

Anybody else with the same Problem?

Any ideas?

Do you have it installed?

 

[rammstein]

Hello Igor,

yes it is installed



The creation of backups actually stopped as well... Last Backup made on 2016-11-08

Hello. Could you please try to run the following command:

/usr/local/psa/admin/bin/pmmcli --get-tasks-list Backup

 

[rammstein]

Ah, interesting output:

Traceback (most recent call last):
  File "/opt/psa/admin/sbin/pmmcli", line 5, in <module>
    import pmmcli

Seems like a problem with Python, do you know how i can fix it?

apt-get install --reinstall python2.7

Does not solve it...

Could you please try to remove *.pyc and *.pyo files inside plesk directory. They will be re-created automatically.

# find /usr/local/psa/ -name *.pyc | xargs rm -f
# find /usr/local/psa/ -name *.pyo | xargs rm -f

Also you can try to reinstall PMM component with

# plesk installer --select-product-id plesk --select-release-current --remove-component pmm
# plesk installer --select-product-id plesk --select-release-current --install-component pmm

Scared me a little bit but worked like a charm!

# plesk installer --select-product-id plesk --select-release-current --remove-component pmm
# plesk installer --select-product-id plesk --select-release-current --install-component pmm

Should have worked as well, but I decided to try Sergey's solution first, because I thought "removing" and "re-installung" could potentially result in an loss of "Backup-Task-Configurations".
With around 40-Domains backingup to an FTP-Repo this would have been a real pain


Thank you to both of you! Problem solved!
