Comment 17 for bug 388911

I'm getting this exact problem on lucid (trac-git 0.0.20090320-1ubuntu2). /usr/lib/python2.6/dist-packages/tracext/git/ exists and contains files, but aside from that, the behaviour is the same as described in the original post:

msched@gandalf:~$ sudo trac-admin /var/local/trac/MadMaze/ resync
Resyncing repository history...
Command failed: Unsupported version control system "git": Can't find an appropriate component, maybe the corresponding plugin was not enabled?

trac was already installed before upgrading the system to lucid, but trac-git was installed only afterwards.
