After setting the server time with the following command:

dpkg-reconfigure tzdata

The syslog service now needs restarted:

service syslog restart

Tail the mail.log to check the entries are stamped with the correct time:

tail -f /var/log/mail/log

If you are trying to packet capture on a remote server as a non root user carry out the following as root:

Add a capture group and add yourself to it:

groupadd pcap
usermod -a -G pcap nonrootuser

Next, change the group of tcpdump and set permissions:

chgrp pcap /usr/sbin/tcpdump
chmod 750 /usr/sbin/tcpdump

Finally, use setcap to give tcpdump the necessary permissions:

setcap cap_net_raw,cap_net_admin=eip /usr/sbin/tcpdump

The script is attempting to insert or update a row with the integer entry taking on either the default value (e.g., of 0 or NULL) or the next AUTO_INCREMENT value.

MySQL is not interpreting this action as valid due to its SQL_MODE being in STRICT mode.

To fix:

/etc/mysql/mysql.conf.d/mysqld.cnf

Change
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

To:
sql_mode=””

Restart MYSQL.

*In my case I had so sql_mode entry so I just appended to the end of the file.

For me it was as simple as enabling the CGI module for apache2:
