Re: "combined" prerm script problem [Bug#337223: fail2ban: leaves garbage around after purge]

["Joe Smith" <unknown_kev_cat@hotmail.com>]

The bug is in the initscript.
LSB mandates that 'stop' not fail if the service is not running.

Replace this code:
"""
if $0 status >/dev/null
then
fail2banpid=`cat $PIDFILE`
else
( $0 status )
echo "Not stopping fail2ban"
exit 1
fi
"""

With code like this:
"""
$0 status >/dev/null
status=$?
if [ $status -eq 0 ];then # It is running
fail2banpid=`cat $PIDFILE`
elif [ $status -eq 3 ];then #It is not running we are done
echo "Done."
exit 0
else
( $0 status )
echo "Not stopping fail2ban"
exit 1
fi
"""

Then everything should run fine.
