This is the situation:
John creates a fantastic app and pushes the code to Bitbucket, we call this repo aww
Alan checks out the master branch of aww, does some awesome changes, and creates a pull request from master to master of the aww repo
Alan becomes unavailable.
There are conflicts.
Please how does John fix the conflicts and merge the work of Alan?
Thank you.
OTHER INFO/EDIT
John tried very hard to checkout the pull request following this post but he is really not able to do it and from this other post it appears to be impossible.
