I successfully upgraded to 7.5.2 using "yum", php, mysql, psa etc. The only issues I'm having are the below. Any suggestions are appreciated.

When I click the the "updater" now I get...
CODE
AutoInstallerManager::getAutoInstaller() failed: AutoInstallerManager::_autoInstallerCall() failed: autoinstaller failed: Empty error message from utility.

0: /usr/local/psa/admin/htdocs/server/autoinstaller_releases.php:12 psaerror(string "AutoInstallerManager::getAutoInstaller() failed: AutoInstallerManager::_autoInstallerCall() failed: autoinstaller failed: Empty error message from utility.")



And when I try to start spamassain using the service panel
CODE
Unable to make action: Unable to manage service by spamd: Empty error message from utility.

0: /usr/local/psa/admin/htdocs/server/restart_services.php:19 psaerror(string "Unable to make action: Unable to manage service by spamd: Empty error message from utility.")
