+hint: You have divergent branches and need to specify how to reconcile them.
+hint: You can do so by running one of the following commands sometime before

+hint:
+hint:   git config pull.rebase false  # merge
+hint:   git config pull.rebase true   # rebase
+hint:   git config pull.ff only       # fast-forward only
+hint:
+hint: You can replace "git config" with "git config --global" to set a default
+hint: preference for all repositories. You can also pass --rebase, --no-rebase,
+hint: or --ff-only on the command line to override the configured default per
+hint: invocation.
