|Websocket connection stuck in FIN_WAIT1 FIN_WAIT2 states|
Any time you see a Fin_Wait state or any wait
state for that matter, we often refer to these as
1/2 sessions. The TCP stack follows a very strict
protocol on the order of requests and responses.
It is because of these rules that it knows how and
when as well as how-hard to attempt to recover by
sending retries. In the instance of any Wait
state the stack knows it's waiting for something.

libfreetype6-dev is the package that I needed.
The issue is that this package installs the header
files needed for the compilation in
/usr/include/freetype2 but the configure script is
looking for the headers in /usr/include/freetype .
So the solution I found was to add a symbolic
link in /usr/include that points to
/usr/include/freetype2 that is called freetype.
This can be done in the termina
