Most likely you truncated your config file somehow. It looks ok. 
I wasn't testing it on 2.4, but i found reference to it: <a href="https://www.mail-archive.com/haproxy@formilux.org/msg37698.html" rel="noreferrer">https://www.mail-archive.com/haproxy@formilux.org/msg37698.html</a> and was able to reproduce it on 2.2 (it was warning in 2.2, became error in 2.3 as described by haproxy message) with this simple config:
<pre><code>defaults
 timeout connect 5000
 timeout client 50000
 timeout server 50000

frontend http_front
 bind *:80
 mode http
 http-request deny
</code></pre>
This config is valid:
<pre><code># haproxy -c -f test.conf
Configuration file is valid
</code></pre>
Now i will truncate it by one byte to reproduce it:
<pre><code># wc -c test.conf
149 test.conf
# dd if=test.conf of=test2.conf bs=1 count=148

I had the same issue and I tried using Editor. but, it didn't work.

<h3>Working Solution:</h3>
<ul>
<li></li>
</ul>

Basically the title. I'm working on upgrading our existing haproxy from 1.5 to the latest version. Because of that, I'm setting up a test case to ensure our old setup can work on it. However, when I try to run it, I get the following error:
<pre><code>[NOTICE] (28948) : haproxy version is 2.4.1-1ce7d49
[NOTICE] (28948) : path to executable is /home/user/test/usr/local/sbin/haproxy
[ALERT] (28948) : parsing [test.cfg:22]: Missing LF on last line, file might have been truncated at position 68.
[ALERT] (28948) : Error(s) found in configuration file : test.cfg
[ALERT] (28948) : Fatal errors found in configuration.
</code></pre>
I've tried looking it up, but I cannot find anything on the error. I've already checked my config file, and it is using the correct Unix format. Also, my test config works for the older version of HAProxy.
<pre><code>global
 stats timeout 30s
 user root
 group root

defaults
 log global
 mode http
 option httplog
 option dontlognull
 timeout connect 5000
 timeout client 50000
 timeout server 50000

frontend http_front
 bind *:9090
 default_backend http_back

backend http_back
 balance roundrobin
 server test.server.com 127.0.0.1:8000
</code></pre>
In addition, I did the following to install haproxy:
<pre><code>tar xvf haproxy-2.4.1.tar.gz
cd haproxy-2.4.1
#vi to Makefile and set PREFIX to PREFIX = /home/user/test/usr/local
make TARGET=linux-glibc
make install
</code></pre>
Is there anything that sticks out regarding my config file? Or did I miss something in the installation process?
