Installation fails when apache is not running as apache.apache

[Yongqin Liu]

after installed launch-control with the Instructions, an "Internal Server Error" occurs when access "http://localhost/launch-control/".

> sudo apt-get install libapache2-mod-wsgi
> sudo a2enmod wsgi
> sudo add-apt-repository ppa:zkrynicki/lava
> sudo apt-get update
> sudo apt-get install launch-control-sqlite launch-control

> prompted for database password just use the default automatically
> generated value.

> The dashboard should now be available at
> http://localhost/launch-control
> Note: the system is available to anyone that can connect to your host,

The reason is that i have changed the apache instance's user and group to apache in "/etc/apache2/envvars" as bellow:

#export APACHE_RUN_USER=www-data
#export APACHE_RUN_GROUP=www-data
export APACHE_RUN_GROUP=apache
export APACHE_RUN_USER=apache

and the process about chat and resolution，please chech the attachment.Including irc chat log and mails

To fix this we'd need to detect unsupported installation attempt and notify the user.

Alternatively we could somehow adapt to the proper user (instead of www-data) but I don't know any interface to query apache for such information.

[Yongqin Liu (liuyq0307)]

when i move the "/usr/local/lib" back with command "sudo mv /usr/local/lib.old/ /usr/local/lib",
"Internal Server Error" happens again.

but if i move /usr/local/lib to /usr/local/lib.old, the error does not happen, and it becames normal.

log info in "/var/log/apache2/error.log" is as bellow, can you help me to resolve this error?

Your /usr/local/lib has lots of incompatible dashboard libraries installed. You need to remove them first.

[Yongqin Liu (liuyq0307)]

but can you tell me which dashboard libraries are incompatible, and how to remove them?

In the "/usr/local/lib/python2.6/dist-packages/", there are libraries for other applications,
for example, there are Babel-0.9.5-py2.6.egg and Trac-0.12.2-py2.6.egg in the directory.

below is the libraries list in "/usr/local/lib/python2.6/dist-packages/":

If you need to use your local libraries please do so with virtualenv not
to mess with system-installed libraries.

 From the list below I would remove everything except for Babel and
Track. In general as soon as you start putting python libraries in
/usr/local we cannot support you.

Best regards
