gh-deploy issue

[mdeliw]

Can someone help me with this issue:
`| => docker run --rm -it -v ~/.ssh:/root/.ssh -v ${PWD}:/docs squidfunk/mkdocs-material gh-deploy
INFO - Cleaning site directory
INFO - Building documentation to directory: /docs/site
INFO - Documentation built in 0.79 seconds
INFO - Copying '/docs/site' to 'gh-pages' branch and pushing to GitHub.
ERROR - Failed to deploy to GitHub with error:
/root/.ssh/config: line 3: Bad configuration option: usekeychain
/root/.ssh/config: terminating, 1 bad configuration options
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
`

My ~/.ssh/id_rsa.pub is attached to remote. I had to remove UseKeychain yes to make this work.
