Hello! I have an issue with updating ownCloud from ownCloud 9.0.4 (stable) to ownCloud 9.0.6 on ISPConfig 3.1.1p1 (Apache), Debian 8.7. On admin page it says 'A new version is available: ownCloud 9.0.6', and when I click on 'Open updater' I get Code: [UnexpectedValueException] Could not parse a response for config:list. Please check if the current shell user can run occ command. Raw output: Not allowed What to do? Do I need to add some new Shell User via ISPConfig's interface?
