This is another one of those 3-hour debug sessions that ended with a single line of code, all other changes being useless.

I was trying to setup my ChiliProject installation to use gitolite, but here's a gotcha that I think many people will fall into: most gitolite tutorials have the user as gitolite instead of the default git from gitosis tutorials, probably because they're being run side-by-side. Now, when you first install redmine_git_hosting with a git clone, the default settings cause problems.

Once the .git/ directory has been removed and the database migrated, your instinct is to run the webserver and edit the settings. So, if your username isn't git you'll go to http://127.0.0.1:3000/settings/plugin/redmine_git_hosting and change "Git Username" to yours, which I'll assume is gitolite. However, if you didn't go straight to this page, you'll hit my problem: /tmp/redmine_git_hosting/ has already been created! Now, there's a bunch of references to git in that directory, and you'll run into this error over and over:

sudo: unknown user: git
sudo: unknown user: git
sudo: unknown user: git

But you'll never be able to grep for it properly because it's not created inside of your project, but inside of /tmp/. So here's the line you've been waiting for:

rm -r /tmp/redmine_git_hosting
