How to Resolve Frappe Bench Update Errors Caused by Git Conflicts?

Resolve Update Errors

A step-by-step guide to fix 'bench update' failures in Frappe and ERPNext by resetting git repositories, correcting file permissions, and ensuring a clean update process.

When managing a Frappe or ERPNext instance, the `bench update` command is essential for keeping your system up-to-date. However, this process can sometimes fail due to underlying git conflicts, local file modifications, or incorrect file permissions. These issues prevent Bench from cleanly pulling the latest updates from the source repositories.

The following script provides a robust solution by forcefully resetting the core repositories and standardizing file ownership, clearing the way for a successful update. It's a powerful tool for system administrators to overcome common update blockers.

resolve_update.shbash
1# For servers using the 'frappe' user
2sudo chown -R frappe:frappe /home/frappe/.bench
3sudo chown -R frappe:frappe /home/frappe/frappe-bench
4

5cd /home/frappe/.bench
6git reset --hard
7git pull

12# For servers using the 'ubuntu' user (common on cloud providers)
13sudo chown -R ubuntu:ubuntu /home/ubuntu/.bench
14sudo chown -R ubuntu:ubuntu /home/ubuntu/frappe-bench

16cd /home/ubuntu/.bench

Understanding This Code

What It Does

This script resolves common 'bench update' failures by forcefully resetting the Frappe and Bench git repositories to their remote state and correcting file ownership permissions.

When To Use

Use this when 'bench update' fails with git-related errors, such as merge conflicts, local uncommitted changes you wish to discard, or permission denied errors during the update process.

Prerequisites

  • •Shell access (SSH) to your Frappe/ERPNext server
  • •Sudo privileges to run commands as root
  • •Frappe Bench installed on the server

Key Concepts

Important ideas to understand in this code

Bench CLI

Bench is the command-line interface for managing Frappe Framework sites. The 'bench update' command is crucial for applying updates to the framework, apps, and dependencies.

File Permissions (chown)

The 'chown' command changes the user and/or group ownership of files. In Frappe, the bench user (e.g., 'frappe' or 'ubuntu') must own all bench files to run updates and other commands correctly. Incorrect permissions are a common source of errors.

Git Reset (--hard)

This command resets the current branch head and discards all changes in the working directory. It's a powerful way to undo local modifications and resolve conflicts by reverting to the official repository state.

Step-by-Step Tutorial

Follow along to understand how this code works

1

Identify the Correct System User

Before running any commands, identify the user that your Frappe instance runs as. This is typically 'frappe' or 'ubuntu'. You must use the commands corresponding to your user.

bash
# Check running processes to find the user
ps aux | grep bench
Next Step
2

Correct File Permissions

Ensure the correct user owns the .bench and frappe-bench directories. This prevents permission errors during the update. Replace 'frappe:frappe' with your system's user if different (e.g., 'ubuntu:ubuntu').

bash
sudo chown -R frappe:frappe /home/frappe/.bench
sudo chown -R frappe:frappe /home/frappe/frappe-bench
Next Step
3

Reset the Bench Repository

Navigate to the '.bench' directory, which contains the Bench CLI tool itself. Reset any local changes and pull the latest version from the official repository.

bash
cd /home/frappe/.bench
git reset --hard
git pull
Next Step
4

Navigate to the Frappe-Bench Directory

Change directory into your main 'frappe-bench' directory. This directory contains your sites, apps, and the Frappe framework. The next command will operate from here.

bash
cd /home/frappe/frappe-bench
Next Step
5

Run Bench Update

With permissions corrected and repositories reset, you can now run the 'bench update' command. This will pull updates for all apps, run patches, build assets, and restart services.

bash
bench update
