First I followed the instructions from Ariejan.net:

How to setup a Ubuntu development server – Part 1

From the Part 1 instructions I mainly followed the steps after the “Getting SSH up and running” section.  Also under the “WebDAV for SVN” section, I did not want to allow anonymous access, so I edited the last part of the file to look like the following:

 # <limitexcept GET PROPFIND OPTIONS REPORT >
    Require valid-user
 # </ limitexcept >

SSLRequireSSL
</location>

Under the “Authentication” section, use htpasswd instead of htpasswd2.

I followed step 3 in Alaph Zarro’s instructions to generate the certificate under Ubuntu >=Feisty:

Installation of Subversion on Ubuntu, with Apache, SSL, and BasicAuth.

Also from the command line I enabled the default-ssl site with the following commands:

sudo a2ensite default-ssl
sudo /etc/init.d/apache2 reload

After that I was able to use the SVN with https in the URL.

Next was installing Trac.  I again followed the instructions from Ariejan.net:

How to setup a Ubuntu development server – Part 2

Instead of modifying the /etc/apache2/sites-available/default file, I modified the /etc/apache2/sites-available/default-ssl file instead to include the lines.  Also I did not follow the “Webadmin” section as it is for an older version of Trac.

After that I went to the “Admin” section of my new Trac project web interface and removed the items under “anonymous” and added them to “authenticated” instead.

I added new users with the following command:

sudo htpasswd -m /etc/apache2/dav_svn.passwd SOMEUSER

where SOMEUSER is the username to add.

At one point I ran across the following error when I attempted the apache reload:

httpd not running, trying to start
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80

Apparently I forgot to run “sudo” in front of the command, so remember to run “sudo” or else you’ll get the same error.

I may have forgotten some steps.  If I remember them I’ll add them in later.
