Hi @karson tse 

Welcome to Atlassian Community.

By default, git merge command refuses to merge histories that do not share a common ancestor. You can override this by using the --force option, this bypasses the checks and may cause the remote repo to loose commits, so be careful when using it.

Hi  Mikael,

Thank you for the response. I am very new to sourcetree/ git, I was wondering where do I find the force option when pulling?

[Mikael Sandberg]

Pull does not have a force option, only push. For pull you can use the option --allow-unrelated-histories, that will also disable the merge check similar to the --force on push.

Have you made any changes in your local repository? If so, have you pushed those changes up to Bitbucket? If you have not pushed/made any changes, what you could try is to do a rebase instead. there is a checkbox for it when you click on pull.
