That error is happening because you installed Trac 0.11.5 manually (not using debs). Note the /usr/local prefix for tracd. You should remove /usr/local/bin/tracd, or fully path to the tracd installed by the deb, so it will use 0.11.7-1 you just upgraded to.
The tracd installed by the deb is /usr/bin/tracd, as listed on http://packages.ubuntu.com/lucid/all/trac/filelist ** Changed in: trac (Ubuntu) Status: New => Invalid -- trac does not work https://bugs.launchpad.net/bugs/578174 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
