running git instaweb in my repository opens a page that says "403 Forbidden - No projects found". What am I missing?
looks like the debian install of git sets $projectroot globally in a way that confuses instaweb. I removed the $projectroot line from /etc/gitweb.conf and the error went away.
I don't know Git about Git, but you're probably missing the ability to execute on the directory in question, chmod +X it.
check the git-web cgi (the perl), see the directory of the projectroot is same as your currect setting. there are some settings that not in gitweb.conf
Two years later ..
I fixed this problem by stating the projectroot in gitweb.cgi (it's the only value that seems to matter)
And another year later ...
I fixed this problem (F12, git 1.7.2.3) by:
vi .git/gitweb/gitweb.cgi # set DocumentRoot to <root>/.git/gitweb.cgi
GITWEB_CONFIG=.git/gitweb lighttpd -f .git/gitweb/httpd.conf
I didn't dig further to figure out why I needed to do this ...
two year later ...
I fixed this problem by adding this line
Options All ExecCGI FollowSymLinks Includes Indexes
to my httpd.conf file
