Hi Andreas, Thank you for your quick response . I installed mod_guardman and its dependencies from the indicated repo . However the failure still occurs . So , I decided to uninstall them and remove the mod_gearman from /etc/logrotate.d [ BTW that it was empty .... maybe some leftovers from some zypper/yast2 uninsatlls ] . As for squidGuard I changed its associated file in /etc/logrotate.d by adding su squid squid . So far is fine . Question : Are squid and squidGuard mandatory ? Again , many thanks for your help . Best Regards, Nick
