Dear trac users,
I am currently trying to migrate an old trac 0.12.3 trac instance
(www.lyx.org/trac) on CentOS 6, to something more modern.
We have elected to base our new server on Ubuntu Noble (the next LTS
release), which may be a bit optimistic.
So, this is both a fresh installation and an upgrade, since I move the
files to a new environment.
I did my best to follow TracInstall and TracUpgrade, and I have
something that seems to work with tracd, but I get an Internal Server
Error when trying to access to trac in the proper way.
My apache2 configuration snippet is:
<Location /trac>
SetHandler mod_python
PythonInterpreter main_interpreter
PythonHandler trac.web.modpython_frontend
PythonOption TracEnv /home/lyx/www/trac
PythonOption TracUriRoot /trac
PythonOption PYTHON_EGG_CACHE /var/trac/lyx/egg-cache
# For Apache 2.2
<IfModule !mod_authz_core.c>
Order allow,deny
Allow from all
</IfModule>
# For Apache 2.4
<IfModule mod_authz_core.c>
Require all granted
</IfModule>
</Location>
and when I try to load the page, I get very weird errors in apache logs,
which do not make sense to me.
Does this ring a bell to anybody?
Sorry for the long message, I probably give too much information and
miss the useful information at the same time.
JMarc
