How to fix error: Entry 'file.txt' not uptodate. Cannot merge. in Git

GitBEGINNERMEDIUMUpdated Dec 6, 2025· 267 views

Git refuses to merge because local files have uncommitted changes that would be overwritten. This typically occurs during pull, merge, or checkout operations when your working directory contains modifications that conflict with incoming changes.

Quick fix

Fixes error: Entry 'file.txt' not uptodate. Cannot merge.

git status
git diff
  1. Check the status of your working directory
  2. Stash your local changes before merging
  3. Stage files added with --intent-to-add
  4. Restore the problematic file to its clean state
git — error
git status
git diff
error: Entry 'file.txt' not uptodate. Cannot merge.

What this error means

This error occurs when Git detects that one or more files in your working directory have been modified but not committed, and those same files would be overwritten or affected by the merge operation you're attempting. Git is protective of your local work and will not proceed with any operation that could potentially destroy uncommitted changes. The "not uptodate" message specifically indicates that the file in your working tree differs from what Git has recorded in its index (staging area), meaning there are pending changes that haven't been staged or committed. This error commonly appears during `git pull`, `git merge`, `git checkout`, or `git rebase` operations when Git needs to modify files that you've already changed locally.

Typical symptoms

  • Git pull fails with "Entry not uptodate. Cannot merge" error
  • Git merge operation refuses to start
  • Cannot switch branches with git checkout
  • Git stash fails with the same error message
  • The error persists even after running git status showing no changes
  • Rebase operation aborts immediately with this error

Common causes

  1. Uncommitted changes in your working directory conflict with incoming changes
  2. Files added with git add --intent-to-add (-N) that haven't been fully staged
  3. File system inode changes from rsync or copying the repository between systems
  4. Case-sensitivity conflicts when working with files that differ only in case on case-insensitive filesystems
  5. Files marked with --skip-worktree or --assume-unchanged flags
  6. External tools (backup software, file indexers) modifying file metadata without changing content
  7. Corrupted Git index that doesn't match the actual working tree state

How to fix "error: Entry 'file.txt' not uptodate. Cannot merge."

1Check the status of your working directory

First, identify what files Git considers changed:

bash
git status
git diff

This will show you which files have uncommitted changes. If git status shows changes but git diff shows nothing, the issue is likely related to file metadata or index corruption.

2Stash your local changes before merging

The safest approach is to temporarily save your changes using git stash:

bash
git stash
git pull
git stash pop

This saves your local modifications, performs the merge, and then reapplies your changes. If there are conflicts after git stash pop, you'll need to resolve them manually.

3Stage files added with --intent-to-add

If you've used git add -N (intent-to-add), you need to fully stage those files:

bash
# Check for intent-to-add files
git status

# Fully stage the files
git add <filename>

# Or stage all pending files
git add .

After staging, you can either commit these changes or use git stash to temporarily save them.

4Restore the problematic file to its clean state

If you don't need your local changes, you can restore the file to match the repository:

bash
# Using git restore (Git 2.23+)
git restore <filename>

# Or using the older checkout command
git checkout -- <filename>

Warning: This will discard any uncommitted changes to that file.

5Reset the Git index to fix metadata issues

If the error persists despite no visible changes, refresh the Git index:

bash
# Refresh the index
git update-index --refresh

# Or force a hard reset (WARNING: discards all uncommitted changes)
git reset --hard HEAD

The hard reset should only be used if you've backed up any important changes.

6Check for skip-worktree or assume-unchanged flags

Files with special flags can cause this error. Check and remove these flags:

bash
# List files with assume-unchanged
git ls-files -v | grep '^[a-z]'

# List files with skip-worktree
git ls-files -v | grep '^S'

# Remove assume-unchanged flag
git update-index --no-assume-unchanged <filename>

# Remove skip-worktree flag
git update-index --no-skip-worktree <filename>
7Disable ctime checking for external tool interference

If backup software or file indexers are modifying file metadata:

bash
git config core.trustctime false

This tells Git to ignore the ctime (inode change time) when determining if files have changed.

Advanced notes

### Understanding Git's Index

The "not uptodate" error specifically relates to Git's index (staging area). Git maintains three trees: the working directory, the index, and the HEAD commit. When any of these fall out of sync in unexpected ways, this error can occur.

### Case Sensitivity Issues

On case-insensitive file systems (Windows NTFS, macOS HFS+ by default), Git can track files like File.txt and file.txt as separate entries, but the filesystem sees them as one file. This causes persistent "not uptodate" errors. To resolve:

bash
# Check for case conflicts
git ls-files | sort -f | uniq -di

# Fix by removing one variant
git rm --cached <conflicting-filename>

### Repository Synchronization Issues

When copying repositories between systems (via rsync, cloud sync, or manual copying), file inodes change but content remains identical. Git may detect these as modifications. Running git status followed by git checkout -- . or git reset --hard usually resolves this.

### Force Checkout as Last Resort

If all else fails, you can force a checkout:

bash
git checkout -f HEAD

This forces Git to overwrite working tree files, but use with caution as it discards local changes.
