How to resolve git's "not something we can merge" error

I just encountered a problem when merging a branch into master in git. First, I got the branch name by running git ls-remote. Let's call that branch "branch-name". I then ran git merge branch-name command and got the following result:

fatal: branch-name - not something we can merge

How do I resolve this error?

As shown in https://stackoverflow.com/questions/14388625/how-does-not-something-we-can-merge-arise, this error can arise from a typo in the branch name because you are trying to pull a branch that doesn't exist.

If that is not the problem (as in my case), it is likely that you don't have a local copy of the branch that you want to merge. Git requires local knowledge of both branches in order to merge those branches. You can resolve this by checking out the branch to merge and then going back to the branch you want to merge into.

git checkout branch-name
git checkout master
git merge branch-name

This should work, but if you receive an error saying

error: pathspec 'remote-name/branch-name' did not match any file(s) known to git.

you need to fetch the remote (probably, but not necessarily, "origin") before checking out the branch:

git fetch remote-name

It's a silly suggestion, but make sure there is no typo in the branch name!

When pulling from a remote upstream, git fetch --all did the trick for me:

git remote add upstream [url to the original repo]
git checkout [branch to be updated]
git fetch --all
git merge upstream/[branch to be updated]

In other cases, I found the "Not something we can merge" error will also happen if the remote (origin, upstream) branch does not exist. This might seem obvious, but you might find yourself doing git merge origin/develop on a repo that only has master.

I had this issue as well. The branch looked like 'username/master' which seemed to confuse git as it looked like a remote address I defined. For me using this

git merge origin/username/master

worked perfectly fine.

The below method works for me every time.

git checkout master
git pull
git checkout branch-name-to-be-merged
git pull
git checkout branch-name
git pull
git merge branch-name-to-be-merged

It may happen because that branch is not on your local. before merging use

git fetch origin

This answer is not related to the above question, but I faced a similar issue, and maybe this will be useful to someone. I am trying to merge my feature branch to master like below:

$ git merge fix-load

for this got the following error message:

>merge: fix-load - not something we can merge

I looked into above all solutions, but not none of the worked.

Finally, I realized the issue cause is a spelling mistake on my branch name (actually, the merge branch name is fix-loads).

You might also encounter this error if you are not using origin keyword and the branch isn't one of your own.

git checkout <to-branch> 
git merge origin/<from-branch>

You are getting this error because the branch you want to merge doesn't exist on your local repository.

So, first checkout the brach you want to merge into master branch by the following command:

git checkout branch_name_to_merge

After this try to merge it with master branch by the following command:

git merge branch_name_to_merge

This error suggest that the branch from where you want to merge changes (i.e. in you case branch-name) is not present in you local, so you should checkout the branch and fetch the local changes. Checkout to your master branch and fetch, then follow the below steps:

git checkout branch-name
git pull
git checkout new-branch-name
git merge branch-name

I had this issue today when I was merging another branch into mine after directly pulling from master, I had to checkout and pull the branch I was merging first, then I could merge this branch into mine successfully.

git checkout branch-to-merge
git pull
git checkout my-branch-name
git merge branch-to-merge

I must suggest to check all branches or the branch you are looking for is available at first

git branch -r

check from the list

origin/HEAD -> origin/main
origin/feature/branch_1
origin/feature/branch_2
origin/feature/branch_3
origin/feature/branch_4
origin/feature/your branch

Suggestion is to copy the listing from origin itself then do git merge origin/feature/branch_2. Copy pasting will remove typo error.

I got this error when I did a git merge BRANCH_NAME "some commit message" - I'd forgotten to add the -m flag for the commit message, so it thought that the branch name included the comment.

In my opinion i had missed to map my local branch with remote repo. i did below and it worked fine.

git checkout master
git remote add origin https://github.com/yourrepo/project.git
git push -u origin master
git pull
git merge myBranch1FromMain

If the string containing the reference is produced by another Git command (or any other shell command for that matter), make sure that it doesn't contain a return carriage at the end. You will have to strip it before passing the string to "git merge".

Note that it's pretty obvious when this happens, because the error message in on 2 lines:

merge: 26d8e04b29925ea5b59cb50501ab5a14dd35f0f9
 - not something we can merge

We got this error because we had a comma (,) in the branch name. We deleted the local branch, then re-checked it under a new name without the comma. We were able to merge it successfully.

In My case, the Problem was in Branch Name. My new branch name contains brackets, Once I renamed it and remove brackets, It's sorted.

I know it is late to answer but I also faced the same issue so I ran following commands

git checkout master

and then

git pull origin branch-name

It solved my problem

For posterity: Like AxeEffect said... if you have no typos check to see if you have ridiculous characters in your local branch name, like commas or apostrophes. Exactly that happened to me just now.

I suggest checking if you are able to switch to the branch that you are trying to merge with.

I got this error even though the branch I wanted to merge with was in local repository and there were no spelling errors.

I ignored my local changes so that I could switch to the branch (Stash or commit can also be preferred). After this I switched back to the initial branch, and the merge was successful.

The branch which you are tryin to merge may not be identified by you git at present so perform git branch and see if the branch which you want to merge exists are not, if not then perform git pull and now if you do git branch, the branch will be visible now, and now you perform git merge <BranchName>

I had the same problem. I fixed it using the command below:

git checkout main
git fetch
git checkout branch_name
git fetch
git checkout main
git fetch
git merge branch_name

In my case I was trying to execute git commands from a sub-directory of the git repository. Please make sure its the directory you initialized with git and not its sub-directory.

There can be many reasons for the same:

git merge dependabot/npm_and_yarn/storybook/addon-essentials-6.4.19
merge: dependabot/npm_and_yarn/storybook/addon-essentials-6.4.19 - not something we can merge

1. You are having a branch name with special characters.(as in my case): Solution: Checkout a new branch with easy name from the branch which is not able to merge. That could help.

git checkout -b feature-addon
git checkout dev
git merge feature-addon

2. This error can arise from a typo in the branch name because you are trying to pull a branch that doesn't exist.

3. Very silly but it is likely that you don't have a local copy of the branch that you want to merge.. Try git fetch to get it

If you are following old tutorials, insted of master check if the branch is named main or something similar.

The error is telling you that branch-name must be the name of one of your branches.

For me the problem occured when I tried this:

git merge -s ours --no-commit --allow-unrelated-histories <remote name>/develop

So actually I should have written master instead of develop,because master was the branch name of Subtree,not my actual branch.

This may sounds weird, but remember to setup your git email and name:

git config --global user.email "[email protected]"
git config --global user.name "FIRST_NAME LAST_NAME"

For me, the problem was the 'double quotation marks' into merge message. So when I removed the double mark, all magically worked. I hope to help someone. (Sorry for my poor English)

I had a work tree with master and an another branch checked out in two different work folders.

PS C:\rhipheusADO\Build> git worktree list

If you need to just merge the latest commit:

git merge origin/vyas-cr-core 
git push

And is same as what I've always done:

git checkout master # This is needed if you're not using worktrees
git pull origin vyas-cr-core
git push

git rebase the-branch-to-be-merged

I solved the problem using this git command, but rebase is only suited for some cases.

My goal is to merge Branch2 code into Branch1.

I got the below message while merging.

My branches Branch1 and Branch2. Please avail these branches in your project folder.

Initially i have only Branch1 with maser, in this case i got the below mentioned message.

Now I have checked out into Branch2.

Now Branch1, Brnach2 and master all are available in my project folder.

Now the merging steps are begin:

1. git checkout Brnach1
2. git merge Branch2

Finally we merged Brnach2 with Branch1
