Unable to push to certain Repos after 4.0 - 5.0 upgrade

Created by: sivaramsk

I recently upgrade from 4.0 to 5.0. I have two different groups under which there are couple of repos - like this

group1/repo1 group1/repo2 group1/repo3

group2/repo1 group2/repo2

The group1/repo1 has around 15 users using and has no issues for pushing after the upgrade. But the group2/repo1 is failing with the following error when trying to push. I saw some post with the same error https://github.com/gitlabhq/gitlabhq/pull/1719. But that was 6 months ago and I am not sure how relevant the problem is.

As of now I worked around the issue by commenting out the line

use Gitolite::Hooks::Update;

in hooks update script. Since I don't use any update as of now, Am I right here?
