Config variables not defined error.

After updating to PHP 5.5.8, started happening after I updated to PHP 5.5.8 when running ApacheBuddy on my Digital Ocean server (Ubuntu 12.04.3 x64).

Invalid Mutex directory in argument file:${APACHE_LOCK_DIR}
Use of uninitialized value $output[0] in pattern match (m//) at
    /tmp/apachebuddy/apachebuddy.pl line 373 (#1)
    (W uninitialized) An undefined value was used as if it were already
    defined.  It was interpreted as a "" or a 0, but maybe it was a mistake.
    To suppress this warning assign a defined value to your variables.

    To help you figure out what was undefined, perl will try to tell you the
    name of the variable (if any) that was undefined. In some cases it cannot
    do this, so it also tells you what operation you used the undefined value
    in.  Note, however, that perl optimizes your program and the operation
    displayed in the warning may not necessarily appear literally in your
    program.  For example, "that $foo" is usually optimized into "that "
    . $foo, and the warning will refer to the concatenation (.) operator,
    even though there is no . in your program.

The process running on port 80 is not Apache

Any idea what may be causing this?

Hello,

Can you include the complete contents of these files? (Feel free to censor any private data)

/etc/apache2/apache2.conf
/etc/init.d/apache2
/etc/default/apache2

[kopepasah]

Here are the contents of the files. I do not believe they contain any private data, but I am a slightly new to dealing with servers. Feel free to let me know if I missed something.

/etc/apache2/apache2.conf

# This is the main Apache server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.

# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
#   /etc/apache2/
#   |-- apache2.conf
#   |   `--  ports.conf
#   |-- mods-enabled
#   |   |-- *.load
#   |   `-- *.conf
#   |-- conf-enabled
#   |   `-- *.conf
#   `-- sites-enabled
#       `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
#   together by including all remaining configuration files when starting up the
#   web server.
#
# * ports.conf is always included from the main configuration file. It is
#   supposed to determine listening ports for incoming connections which can be
#   customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
#   directories contain particular configuration snippets which manage modules,
#   global configuration fragments, or virtual host configurations,
#   respectively.
#
#   They are activated by symlinking available configuration files from their
#   respective *-available/ counterparts. These should be managed by using our
#   helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
#   their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
#   the default configuration, apache2 needs to be started/stopped with
#   /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
#   work with the default configuration.


# Global configuration

#
# ServerRoot: The top of the directory tree under which the server's

# at <URL:http://httpd.apache.org/docs/2.4/mod/core.html#mutex>);
# you will save yourself a lot of trouble.

Similar issue here. The problems is related to uising envvars con conf files....

Examining your Apache configuration...
Uncaught exception from user code:
Unable to open file: /etc/apache2/${GIS_MASTER_ROOT}/apache/vhost_box_7007.conf
at apachebuddy.pl line 91

GIS_MASTER_ROOT is defined in envvars to a full path of a config file we use as vhost

It is then included like this on apache2.conf
Include ${GIS_MASTER_ROOT}/apache/vhost_xxxx.conf

I welcome pull requests. Is anyone able to write the code rather than post issues?
