Git failed to submit data error: failed to push some refs to’’

Load code cloud use tutorial address:
Problem a: execute the Git remote add origin
Fatal: Remote Origin Already exists.
When this problem occurs, Git Remote displays all the remote libraries and USES the command Git Remote RM Origin to delete the origin.

Issue 2: git push-u origin master pushes the local repository to github
fatal: I don’t handle protocol ‘[email protected]
This problem, use the command git remote add origin

question 3: perform $git push -u origin master
the Username for ‘’
! [rejected] master – & gt; Master (the fetch first)
error: failed to push some refs to ‘’
hint: Updates were rejected because the remote contains work that you do
hint: Not have mature. This is usually caused by another repository pushing
hint: To the same ref. You may want to first integrate the remote changes
hint: (e.g., ‘git pull… ‘) before pushing again.
hint: See the ‘Note about fast-forward ‘in ‘git push –help’ for details.
The main reason for the error is that there is already a README file on git repository, so there may be conflicts during submission. In this case, you need to choose to keep the online file or discard the online file. If you discard the online document, you need to choose to force push when pushing, which requires the following command

git push origin master -f

If you choose to keep the readME file online, you need to execute it first

git pull origin master

8. Git push-U Origin Master
Here, an error message appears:
error: failed to push some refs to ‘’
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Merge the remote changes (e.g. ‘git pull’)
hint: before pushing again.
hint: See the ‘Note about fast-forwards’ in ‘git push –help’ for details.
The push failed because a file was initialized on GitHub. The files in the remote repository are newer than the local ones, so to use Git Pull you need to grab the latest file, merge it with the local file and commit it.
