Issue Error when updating to 18.0.50 and during plesk repair installation

[opus68]

Server operating system version

CentOS Linux 7.9.2009

Plesk version and microupdate number

Plesk Obsidian 18.0.50

I ran into a problem report when updating two servers from 18.0.49 to 18.0.50. When trying to "repair plesk installation" the same problem re-appears and repair fails. However, "plesk repair all -n" flags no errors or warnings.

Please see below the relevant excerpt from the installation log.

Thanks!

Hi all,

some added information: it seems to me that the "ReportUsage" daily maintenance task is being called during upgrade/repair and returns a warning which may be the culprit. Running the daily maintenance task manually gives

plesk daily -f ReportUsage
PHP Warning: Trying to access array offset on value of type null; File: /usr/local/psa/admin/plib/ServerInfo/System.php, Line: 349

PHP Warning:  Trying to access array offset on value of type null in /usr/local/psa/admin/plib/ServerInfo/System.php on line 349
PHP Warning: Trying to access array offset on value of type null; File: /usr/local/psa/admin/plib/ServerInfo/System.php, Line: 360

PHP Warning:  Trying to access array offset on value of type null in /usr/local/psa/admin/plib/ServerInfo/System.php on line 360

I don't think this was the case before upgrade to 18.0.50.

Does anybody observe the same behaviour? I am not aware of any changes to the server configuration that may be causing that.

Thanks!

Hi @opus68, thank you for reporting this here. According to developers, this is a known issue that has aready been fixed. The fix will become available in version 18.0.51. The current warning is a warning only. It does not have a severe impact on anything and can be ignored for now. Your system should run as expected on the current 18.0.50 version.
