Errors upgrading tot plesk 12.08 from 11.5.30

[JobBbb]

Hello everyone,

I tried today to upgrade to 12.08 from the plesk webinterface, but I received an error while upgrading. Now the 11.5 control panel is broken. Thought I can still access the upgrade utility. But upgrading to 12.08 doesn't work.


The error I receive is:
Running rpm_check_debug
Fatal error during packages installation: [u'ERROR with rpm_check_debug vs depsolve:', 'psa-logrotate is needed by plesk-service-node-utilities-12.0.18-cos6.build1200140606.15.x86_64', u'Please report this error at http://bugs.centos.org/set_project....centos.org/bug_report_page.php?category=yum']

I'm using CentOS release 6.5 (Final)

Attached you can find the installation log. Anyone any idea?
