git - your branch and 'origin/xxx' have diverged

git - your branch and 'origin/xxx' have diverged

Git error (not after rebase, see below):

Your branch and 'origin/xxx' have diverged,
and have 1 and 1 different commit(s) each, respectively.

Error is caused by two independent commits - one (or more) on the local branch copy and other - on the remote branch copy (for example, commit by another person to the same branch)

History looks like:

... o ---- o ---- A ---- B  origin/branch_xxx (upstream work)
                   \
                    C  branch_xxx (your work)

Most easy way to solve - is to rebase commit C to the remote state:

$ git rebase origin/branch_xxx

The history will look like this:

... o ---- o ---- A ---- B  origin/branch_xxx (upstream work)
                          \
                           C'  branch_xxx (your work)

The same Git error after rebase:

Your branch and 'origin/xxx' have diverged,
and have 1 and 1 different commit(s) each, respectively.

In this case this is normal and expected, your local branch is different then origin version because of rebase.

For example, we have a history like this:

... o ---- o ---- A ---- B  master, origin/master
                   \
                    C  branch_xxx, origin/branch_xxx

Now we want to rebase branch_xxx against the master branch:

$ git checkout branch_xxx
$ git rebase master

And we get "Your branch and 'origin/branch_xxx' have diverged" because the history now is this:

... o ---- o ---- A ---------------------- B  master, origin/master
                   \                        \
                    C  origin/branch_xxx     C' branch_xxx

If you absolutely sure this is your case then you can force Git to push your changes:

$(think twice before this) git push origin branch_xxx -f
