Gerrit replicating to gitolite fails

[Raghavendra Pathi]

I have configured the replication with following configurations



    $cat /var/gerrit/review_site/etc/replication.config
    [gerrit]
      autoReload=true
    [remote "bt-git"]
      projects = ^vt-(.*)$
      push = refs/heads/*:refs/heads/*
      url = g...@git.something.com:/${name}.git



My ssh config file looks like this one,



    Host git
      HostName git.something.com
      User git
      IdentityFile /var/gerrit/.ssh/id_rsa
      StrictHostKeyChecking no
      UserKnownHostsFile /dev/null



Although I have already added the right set of hostkeys in my ~/.ssh/known_hosts the replication plugin fails with the following stacktrace


    [2017-08-02 13:08:55,194] [a6b3228d] Replication to g...@git.something.com:/vt-test.git started...

However I am able to clone the repository from the same machine and it works seamlessly.

Gitolite in general reserves "update" hook for itself and for gerrit replication to work you need to get rid of it on destination repository
