Using git 1.6.4.2, when I tried a git pull I get this error:
error: unable to resolve reference refs/remotes/origin/LT558-optimize-sql: No such file or directory From git+ssh://remoteserver/~/misk5 ! [new branch] LT558-optimize-sql -> origin/LT558-optimize-sql (unable to update local ref) error: unable to resolve reference refs/remotes/origin/split-css: No such file or directory ! [new branch] split-css -> origin/split-css (unable to update local ref) I've tried git remote prune origin, but it didn't help.

Try cleaning-up your local repository with:
$ git gc --prune=now $ git remote prune origin man git-gc(1):
git-gc - Cleanup unnecessary files and optimize the local repository git gc [--aggressive] [--auto] [--quiet] [--prune=<date> | --no-prune] Runs a number of housekeeping tasks within the current repository, such as compressing file revisions (to reduce disk space and increase performance) and removing unreachable objects which may have been created from prior invocations of git add. Users are encouraged to run this task on a regular basis within each repository to maintain good disk space utilization and good operating performance. man git-remote(1):
git-remote - manage set of tracked repositories git remote prune [-n | --dry-run] <name> Deletes all stale remote-tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>". Happened to me as well. In my case, the bad ref was master, and I did the following:
rm .git/refs/remotes/origin/master git fetch This made git restore the ref file. After that everything worked as expected again.
16This did the job for me:
git gc --prune=now For me, it worked to remove the files that are throwing errors from the folder .git/refs/remotes/origin/.
I just would like to add one of the possible causes of a broken Git reference.
Possible root cause
On my system (Windows 7 64-bit), when a BSOD happens, some of the stored reference files (most likely currently opened/being written into when the BSOD happened) are overwritten with NULL characters (ASCII 0).
As others mentioned, to fix it, it's enough to just delete those invalid reference files and re-fetch or re-pull the repository.
Example
Error message:
cannot lock ref 'refs/remotes/origin/some/branch': unable to resolve reference 'refs/remotes/origin/some/branch': reference broken
Solution:
Delete the reference refs/remotes/origin/some/branch which is stored in the file %repo_root%/.git/refs/remotes/origin/some/branch.
Try it:
git gc --prune=now git remote prune origin git pull Explanation: It appears your remote repo (in Github / bitbucket) branches were removed ,though your local references were not updated and pointing to non existent references.
In order to solve this issue:
git fetch --prune git fetch --all git pull For extra reading - Reference from Github documentation :
0git-fetch - Download objects and refs from another repository
--all Fetch all remotes.
--prune After fetching, remove any remote tracking branches which no longer exist on the remote.
Execute the following commands:
rm .git/refs/remotes/origin/master git fetch git branch --set-upstream-to=origin/master 1Just in case, if you need to know what is
.git/refs/remotes/origin/master, you would read the Remotes section in Git References.
I had this same issue and solved it by going to the file it was erroring on:
\repo\.git\refs\remotes\origin\master This file was full of nulls, I replaced it with the latest ref from github.
1In my case, the problem was solved after I've deleted all the remove reference files under the directory .git.
If you look at the message, it would tell you which files you need to delete (specifically).
The files to delete sit under .git/refs/remotes.
I've just deleted all the files there, and ran gc prune
git gc --prune=now After that, everything works just fine.
2git fetch --prune fixed this error for me:
[marc.zych@marc-desktop] - [~/code/driving] - [Wed May 10, 02:58:25] [I]> git fetch error: cannot lock ref 'refs/remotes/origin/user/janek/integration/20170505': 'refs/remotes/origin/user/janek/integration' exists; cannot create 'refs/remotes/origin/user/janek/integration/20170505' From github.com:zooxco/driving ! [new branch] user/janek/integration/20170505 -> origin/user/janek/integration/20170505 (unable to update local ref) From github.com:zooxco/driving [marc.zych@marc-desktop] - [~/code/driving] - [Wed May 10, 02:58:30] [I]> git fetch --prune - [deleted] (none) -> origin/user/janek/integration This assumes that the offending branch was deleted on the remote, though.
You can also add this to ~/.gitconfig to automatically prune when running git fetch:
[fetch] prune = true If this error “unable to update local ref” is reoccurring, even after applying either the answer by Vojtech Vitek or Michel Krämer you may you may have a bad ref on your local AND master repository.
In this case you should apply both fix's without pulling or pushing in between ...
rm .git/refs/remotes/origin/master git fetch git gc --prune=now git remote prune origin A permanent resolution for me was only achieved after applying both fix's before push/pull.
1For me, I solved it this way:
rm .git/refs/remotes/origin/master git fetch After that I get this message from github.
There is no tracking information for the current branch
So next I did to fix this was:
git branch --set-upstream-to=origin/master master git pull To Answer this in very short, this issue comes when your local has some information about the remote and someone changes something which makes remote and your changes unsync.
I was getting this issue because someone has deleted remote branch and again created with the same name.
For dealing with such issues, do a pull or fetch from remote.
git remote prune origin or if you are using any GUI, do a fetch from remote.
Try this:
git pull origin Branch_Name Branch_Name, the branch which you are currently on.
If you do only a git pull, it pulls all other created branch name as well.
So is the reason you are getting this:
! [new branch] split-css -> origin/split-css (unable to update local ref) I was able to work with
git remote update --prune For me, I had a local branch named feature/phase2 and the remote branch was named feature/phase2/data-model. The naming conflict was the cause of the problem, so I deleted my local branch (you could rename it if it had anything you needed to keep)
If git gc --prune=now dosen't help you. (bad luck like me)
What I did is remove the project in local, and re clone the whole project again.
1I'm using Tower and for some reason my folder name was .git/refs/remotes/origin/Github. Changing it to lowercase .git/refs/remotes/origin/github solved the issue.
I had same issue. i follow following steps
1)switch your branch which having issue to other branch
2) delete that branch
3) checkout again.
Note:- You can stash you uncommitted changes and put it back again.
I used git prune origin and that did the work.
Writing down a specific case that might cause this problem.
One day I pushed a branch named "feature/subfeature", while having "feature" branch on remote.
That operation worked fine without any error on my side, but when my co-workers fetched and/or pulled any branch, they all had the exact same error message unable to update local ref, cannot lock ref 'refs/remotes/origin/feature/subfeature.
This was solved by deleting feature branch on remote(git push --delete origin feature) and then running git remote prune origin on my co-workers' repo, which generated messages including * [pruned] origin/feature.
So, my guess is git fetch was trying to create subfeature ref in feature folder on git internally(.git/...), but creating folder failed because there was feature ref already.
Try this: git branch --unset-upstream
I was facing the problem earlier but I just solved it when I saw this command on the terminal.
Error: cannot lock ref" simply means information in /refs are corrupted and Git cannot continue to create index.lock file.
Quick fix : Remove and re-add remote.
-1 Copy the SSH git URL of your existing remote. You can print it to the terminal using this command:
git remote -v
2- Remove the remote from your local git repo:
git remote rm origin
3- Add the remote back to your local repo:
git remote add origin :your-username/repo-name.git
4- Prune remote origin Users across online forums have reported that the command below worked for them:
git remote prune origin
5- Clean up and optimize local repository git gc --prune=now

0When it is caused by Google Drive desktop.ini files
Google Drive client for Windows creates desktop.ini files in each folder. If your git repository is in a directory that is being synced with Google Drive, then the desktop.ini files will cause the git repository to fail with something like:
cannot lock ref 'refs/remotes/origin/desktop.ini': unable to resolve reference 'refs/remotes/origin/desktop.ini': reference broken To solve this error you might wnat to delete the desktop.ini files in your git repository.
If you have WSL setup, then you can use the following command to delete the desktop.ini files:
Note: ⚠️ This command will delete all
desktop.inifiles in all.gitdirectories in your<project_directory>.
find <project_directory> -type d -name .git -print0 | xargs -0 -I {} find {} -type f -name desktop.ini -print0 | xargs -0 -I {} rm -vf {} If you just want to delete the desktop.ini files in a specific .git directory, then you can use the following command:
find <.git_directory> -type f -name desktop.ini -print0 | xargs -0 -I {} rm -vf {} I had the same problem with composer update. But for me it only worked after I cleared the composer cache and after deleting the content of the vendor folder:
rm -rf vendor/* git gc --prune=now git pull composer clear-cache composer update my/package Got this issue when trying to clone from a git bundle created file, none of the other answers worked because I couldn't clone the repo (so git gc and removing/editing files was out of the question).
There was however another way to fix this - the source file of a .bundle file was begining with:
# v2 git bundle 9a3184e2f983ba13cc7f40a820df8dd8cf20b54d HEAD 9a3184e2f983ba13cc7f40a820df8dd8cf20b54d refs/heads/master 9a3184e2f983ba13cc7f40a820df8dd8cf20b54d refs/heads/master PACK.......p..x...Kj.0...: (and so on...) Simply removing the fourth line with vim fixed the issue.
I had this issue while using SourceTree. I tried to pull again and it worked. I think I Was witching branches (checkout) too fast :).
My situation is a bit different from the poster's because my repository has been relatively cooperative, without any apparent corruption.
Had the same msg but with a directory, got a failed msg on pull.
git --prone did not help me either. Turns out there was a file with the same name as a directory created remotely.
Had to go to .git\logs\refs\remotes\origin and erase the locale file - then pull again, all good.
# remove the reference file of the branch "lost" rm -fv ./.git/refs/remotes/origin/feature/v1.6.9-api-token-bot-reader # get all the branches from the master git fetch --all # git will "know" how-to handle the issue from now on # From github.com:futurice/senzoit-www-server # * [new branch] feature/v1.6.9-api-token-bot-reader -> # origin/feature/v1.6.9-api-token-bot-reader # and push your local changes git push
