TRAC has trouble with Ubuntu's {{{WartyWarthog}}} release; it needs versions of python-SQLite and clearsilver that aren't available on Warty. So I upgraded my fresh Warty to the {{{HoaryHedgehog}}} release. A fresh Hoary install should be ok but I didn't test that.

To upgrade I changed my etc\apt\sources.list to look like the one found [http://www.ubuntulinux.org/wiki/GuideToHoary/view?searchterm=hoary%20sources.list here,] or [wiki:TracOnUbuntu#sources.list] then ran the following commands: 
{{{
sudo apt-get update 
sudo apt-get upgrade
}}}

You can take a nice long break while Hoary is downloaded and installed. 

Once that's done, we have a brand-new Hoary install. The rest of these instructions look painful, but really the hardest part is now over. With a fast net connection, you can do the rest of this in about ten minutes.

We need to install a few more things:

{{{
sudo apt-get install openssh-server
sudo apt-get install trac
sudo apt-get install libapache2-svn
}}}

Configure Apache for DAV (svn needs it) by editing '''/etc/apache2/sites-available/default'''. When you're done the file will look like this (I think my changes are pretty obvious - they are preceded by the comment lines IN ALL CAPS):

We need to enable the apache2 DAV mod with the following command:

{{{
sudo ln -s /etc/apache2/mods-available/dav.load /etc/apache2/mods-enabled/dav.load
}}}

I installed my Subversion repository at '''/var/svn/project'''. So I did a quick starting config of subversion with the following commands:
{{{
mkdir /var/svn
mkdir /var/svn/project
mkdir /tmp/project
mkdir /tmp/project/branches
mkdir /tmp/project/tags
mkdir /tmp/project/trunk
svnadmin create /var/svn/project
svn import /tmp/project file:///var/svn/project -m "initial import"
rm -rf /tmp/project
}}}

Some permissions changes and an apache restart are now needed:
{{{
sudo chown -R www-data /var/trac/project
sudo chown -R www-data /var/svn/project
sudo chown -R www-data /usr/share/trac
sudo apache2 -k restart
}}}

Test by going to !http://servername/svn/project

If this works, your Subversion install is up and running! Now let's finish the Trac install.

I put my trac environment at /var/trac/project. I'm not using the mod_python extentions at the moment. First I ran 
{{{
mkdir /var/trac
trac-admin /var/trac/project initenv 
}}}
The "trac-admin" command above prompted me to enter the project name (''project''), the path to the trac environment (''var/trac/project''), and the path to the Trac templates directory (''usr/share/trac/templates''); then it printed out a bunch of stuff. If there are no errors you should now be able to surf to your Trac site at '''!http://servername/cgi-bin/trac.cgi'''

At the time I did my install, there was one glitch in the Ubuntu Universe Trac installer. It doesn't install the neo_cgi.so file needed in the python2.4 directory space. So when I surfed to my Trac site, I got a complaint specifically about this missing file. I was able to fix this by symlinking the python2.3 version like so:

{{{
sudo ln -s /usr/lib/python2.3/site-packages/neo_cgi.so /usr/lib/python2.4/site-packages/neo_cgi.so
}}}

OPTIONAL: create a redirect file called /var/www.index.html with this one line:
{{{
<META HTTP-EQUIV="Refresh" CONTENT="0; URL=http://10.0.0.102/cgi-bin/trac.cgi">
}}}

... with this change, you can get to Trac with '''!http://servername''' instead of the more cumbersome '''!http://servername/cgi-bin/trac.cgi'''
