从远程分支重新设置了git的基准，重新基准后，分支信息丢失了

Question

I have a remote branch : let's say X and i have a mirror or above : Let's say Y With in Y, i have another branch feature.

I wanted to rebase feature with X, so tried following command : git rebase X/master Y/feature

After this, branch info is lost, and i am not able to push any changes.

Any pointers??

As Jubobs noted in a comment , you can't do that.

More specifically, as the documentation notes:

git rebase ... [ upstream [ branch ]]

If branch is specified, git rebase will perform an automatic git checkout branch before doing anything else. ...

In your example you wrote:

git rebase X/master Y/feature

Here, upstream is X/master , and branch is Y/feature , so the rebase process starts by doing git checkout Y/feature .

If you try this yourself, you will see:

 Note: checking out 'Y/feature'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. 

So, git rebase will start by putting you into "detached HEAD" state. It will then do the usual rebase operation using X/master as the upstream for the newly-detached HEAD.

This has a well-defined meaning, but is probably nothing like what you intended (though it's not clear to me what you did intend).
