Permission denied accessing the local Git repository '/home/user/foo/.git'

[udam.d...@gmail.com]

Hello,

I'm trying to set up reviewboard on Fedora linux. I've already disabled SELinux due to other issues starting up Reviewboard. Running apache with the other recommended settings. Now I have review board setup but cannot get my git repository set up (even after trying for a day).

Here's my issue:

- I could not get the get repository setup with remote pointing to my private github repository.

- Since then I have setup a local git repo using ssh 

- I've put the local git repo in multiple places (/tmp/foo, /home/user/foo etc) yet continue to get the same error in the setup repo screen where it says "permission denied accessing the local git repository"

- In the mirror path, I specify ssh://g...@git.host.lan/github/foo.git

- I've tried giving the apache user ownership of the foo directory and the .git directory and given ugo+rwx on both of those directories.

If I specify only the ssh://g...@git.host.lan/github/foo.git as the path and leave the mirror path empty OR specify the same for the mirror path, I can create the repo but cannot post a review to the repo. It fails with the error:

Your review request still exists, but the diff is not attached.

http://host.domain.lan/r/4/

- Here I tried to post from my laptop which also has the git repository cloned from git hub.

Any help will be much appreciated!

Hi,

Just to check, is this repository local to the Review Board server, or remote?

If local, make sure that your web server's user (usually apache or www-data) has read access to everything under the git repository.

if remote, you're going to need to use a service like gitweb/cgit/gitlab/etc, since Git has no support for fine-grained remote access to files/commits. We have some docs on how to do this: https://www.reviewboard.org/docs/manual/2.0/admin/configuration/repositories/#raw-file-urls

Hi Christian,

Thank you for the quick response. I'm using local repo due to not having the gitweb/cgit etc. I locally cloned the git repository under my home directory. The whole repository has read privileges to all users of the system (chmod -R ugo+r foo) already.

However, the error message when I try to save the repository configuration is always "Permission denied accessing the local Git repository '/home/user/foo/.git'"

Are there any log files where I can see specific logs related to the error?

I've also installed the beta 2.5 version and tried with that but get the same error message.

Thanks again!

Hi,

There's no additional logs for this, as that's basically all the information we're given. That error is coming straight from Git.

Best way to reproduce for testing is to `sudo -s` to your web server's user, then attempt to do a `git ls-remotes` on that repository. See if you get an error.

This does sound like either a permissions issue or SELinux. However, it could also be that the user can't access some parent directory of the repository.

Ok yes, that was the problem. 

For anyone thats in this bad situation in the future, the way to figure out the issue is as follows:

As Christian mentioned, do: 

sudo -su apache (or user who runs apache)

cd to git repo

git ls-remote

In my case, it was failing to connect via ssh (public key denied)

My solution was to:
create a .ssh directory in the home directory of the user (apache). In my case, this was in /usr/share/httpd

in the .ssh directory, i copied over my ssh keys to connect to the git hub repo

cloned the repo under the /usr/share/httpd directory

This succeeds if/when the ssh keys are properly set up.

Once this succeeds, you can submit the repository form with the path set to the local .ssh path AND the mirror path set to the ssh://.... path of your repo.

the misleading thing here is the directory might be given all the permissions needed but still gives that same error message when the ssh public key auth is failing.

One last question: Do we need to manually keep the git repository up-to-date? e.g. cron tab?

Thanks again for the help!!
