Unable to apply platform patches to Gateway 10 appliance

Products

• CA API Gateway

Issue/Introduction

When  trying to install the platform patch Layer7_API_PlatformUpdate_64bit_v10.X-CentOS-2020-10-21.L7P on API Gateway 10 you get an error and the patch is not installed .

If you check the log file   (/var/log/layer7-patchlog)  there is a error :

Thu Apr 8 11:13:59 '2021: ERROR' - The rsyslog configuration file '(/etc/rsyslog.conf)' syntax is not valid. Exiting

Environment

Release : 10.0

Component : API GATEWAY

Cause

This occurs when a exported  configuration is imported in Gateway 10 using the the import configuration wizard which generates a new rsyslog.conf file .

Resolution

When you import a configuration the wizard creates a new config file which is not valid for the current syslog version .

/sbin/rsyslogd -c3 -f /etc/rsyslog.conf -N 1 shows the problem is in line 61 

The problem is the line 61 in my case which looks like 

# Everybody gets emergency messages
*.emerg                                                 *

Comment out the line *.emerg   

# *.emerg   

Verify is the file is valid now with

/sbin/rsyslogd -c3 -f /etc/rsyslog.conf -N 1

rsyslogd: version 8.24.0-57.el7_9, config validation run (level 1), master config /etc/rsyslog.conf
rsyslogd: End of config validation run. Bye.

If so reapply the platform patch 

This will be fixed in future release.
