GitLab push error: LFS objects are missing

This happened to our repositories on GitLab when they introduced their own LFS support recently. If you want to continue to use your own LFS then the process is rather painful - you need to disable their own LFS support on each repository, but there doesn't seem to be a web option for it, you need to do it via their command line API:

1. Install the python gitlab command line API: pip install python-gitlab
2. Setup a private gitlab token for your account, generate it on the Access Tokens portion of your account profile.

3. Write a configuration file out to ~/.python-gitlab.cfg:

   [global]
   default = yourrepo
   ssl_verify = true
   timeout = 20
   
   [yourrepo]
   url = https://gitlab.com/
   private_token = <your API key from the settings tab on gitlab.com>
   

4. Grab your gitlab project id from the top of the settings web page

5. gitlab project update --lfs-enabled false --id <Your project id>

Some of our developers reported that even this didn't work and they had to resort to sending a manual HTTP PUT request to https://gitlab.com/api/v4/projects/<Your project id>?lfs_enabled=false with a Private-Token header set to your private token. For example, with CURL:

 curl -X PUT --header "Private-Token: <private token>" -F "lfs_enabled=false" https://gitlab.com/api/v4/projects/<project id>
