After upgrade to Plesk 17.8 email notification is sent about KAV updates hourly

Symptoms

After upgrade to Plesk 17.8, Plesk sends the following mail message after every cron task execution:

CONFIG_TEXT: Loading engine...
Current product version: 8.5.1.5
Initializing engine...
Using xml-file: /opt/kav/sdk8l3/bin/settings.xml.

LICENSE INFO:
Key file: kav.key
Expiration date: 29/11/2019
Operation result code: 0x00000000. Success
/opt/kav/sdk8l3/bin/kav8update: line 14: service: command not found

Cause

It is a Plesk bug with ID PPPM-8459, which will be fixed in further updates.

Resolution

Reconfigure update script to write the output of cronjob to log file /var/log/kav-update.log instead of sending it by email.

1. Connect to Plesk server via SSH

2. Back up the file /opt/kav/sdk8l3/bin/kav8update:

   # cp /opt/kav/sdk8l3/bin/kav8update /opt/kav/sdk8l3/bin/kav8update.bkp

3. Modify /opt/kav/sdk8l3/bin/kav8update as follows:

   CONFIG_TEXT: #!/bin/bash
   SDK_HOME=/opt/kav/sdk8l3
   export KL_PLUGINS_PATH="$SDK_HOME/lib"
   export LD_LIBRARY_PATH="$KL_PLUGINS_PATH:$LD_LIBRARY_PATH"
   $SDK_HOME/bin/keepup2date8 --download --licinfo --simplelic --version --xmlfile $SDK_HOME/bin/settings.xml >> /var/log/kav-update.log 2>&1
   RET=$?
   ### Return codes are detailed in updatersdk.h

   0)
   # 0 - Success
   service kavehost reload > /dev/null 2>&1
   ;;
   10|20)
   # 10 - All files are up-to-date
   # 20 - An operation did not complete because the current version of definitions is newer than the version in the source
   RET=0
   ;;
   esac
   exit $RET
