As a result, the ability to push code stops working suddenly, which can be a cause of frustration. It occurs when a developer attempts to push committed code to an external git repository, while the local repository has not yet been updated with any changes made in the remote repo. What is ‘failed to push some refs to’ errorįailed to push some refs to is a Git error that many developers frequently face. Kubernetes Cost Optimization Cost Factors, Challenges and Solutions.
However, in this scenario, Git does not allow us to do git push without specifying the remote branch specifically, for the branches whose branch names do not match between the local branch and remote branch. If we are going to create a new branch called temp_3 based on local branch temp_2, make some changes, and push it to the remote branch temp_2 in the remote repo, we would need to set the upstream for the local branch temp_3 to remote temp_2. Git branch -set-upstream-to=origin/temp_2 temp_2 It should be noted that the following three commands are equivalent: 1 Next time when you try to push some change to the remote branch, you would just simply do git push without branch name, because the branch already knows what its upstream is. 1īranch 'temp_2' set up to track remote branch 'temp_2' from 'origin'. If we are going to create a new branch called temp_2 and push it to the remote branch temp_2 in the remote repo, running the following commands containing git push -u would work. This is because nothing has been updated on the local temp_1 branch, so the remote temp_1 branch is up-to-date.
GIT SET UPSTREAM TO DIFFERENT BRANCH UPDATE
If we are going to create a new branch called temp_2 based on existing branch temp_1 and push it to the remote branch temp_1 in the remote repo, running the following commands containing git push would update the remote branch temp_1 in the remote repo. The drawback of doing this is that next time when you try to push some change to the remote branch, you would still need to type the branch name with git push, which might be tedious. If the branch does not exist, it will create a branch for us in the repo. 1Įven though the current branch does not have an upstream branch, we specifically tell it to push to a branch. However, running the following commands containing git push would actually work. We can validate this by running the following command. To push the current branch and set the remote as upstream, useīecause the current branch has not been set the upstream branch, so it does not know where the commit should go in the remote repo and will complain to the user. 1įatal: The current branch temp_1 has no upstream branch. If we are going to create a new branch called temp_1 and push it to the remote branch temp_1 in the remote repo, running the following commands containing git push would fail. We assume we are in a repo that already has a master branch both locally and remotely. In this blog post, we will dig into this and try to understand the mechanism behind it. Sometimes people are confused about the difference between git push and git push -u.
