I just upgraded to Trac 0.11.4 on Ubuntu and I noticed that the /usr/share/trac/templates directory no longer exists. As a result, in my trac.ini, the templates_dir variable is not set ([inherit] section) and where the Trac logo is supposed to be I see the alt text (please configure the [header_logo] section in trac.ini).
Does anyone know where either the templates directory is located or the global trac.ini?
Apperantly the /usr/share/trac/templates directory only exist if you install Trac from the Ubuntu repositories (apt-get install trac). However, when you install Trac manually (when you want the latest version e.g.) this location is not created during installation.
You don't necessarily need a global trac.ini. If the logo is missing from you Trac instance you can easily add it by modifying the [header_logo] section of the conf/trac.ini of your Trac installation:
[header_logo] alt = height = -1 link = http://example.org src = common/trac_banner.png width = -1
