How to fix remote: error: GH003: This repository was archived by the owner. It is now read-only. in Git

# Visit the repository on GitHub
# Look for the yellow banner at the top that says:
# "This repository has been archived by the owner. It is now read-only."

# You can also check via the GitHub API
curl -s https://api.github.com/repos/OWNER/REPO | grep archived
# Output: "archived": true

# On GitHub, click the "Fork" button on the archived repository
# This creates a copy under your account that you can modify

# Clone your fork
git clone https://github.com/YOUR-USERNAME/REPO.git
cd REPO

# Add the original as upstream (for reference)
git remote add upstream https://github.com/ORIGINAL-OWNER/REPO.git

# Make your changes and push to YOUR fork
git add .
git commit -m "Your changes"
git push origin main

# First, create a fork on GitHub (via the web interface)

# Check your current remote
git remote -v
# origin  https://github.com/ORIGINAL-OWNER/REPO.git (fetch)
# origin  https://github.com/ORIGINAL-OWNER/REPO.git (push)

# Update the remote to point to your fork
git remote set-url origin https://github.com/YOUR-USERNAME/REPO.git

# Verify the change
git remote -v
# origin  https://github.com/YOUR-USERNAME/REPO.git (fetch)
# origin  https://github.com/YOUR-USERNAME/REPO.git (push)

# Now push your changes
git push origin main

# After unarchiving, verify you can push
git push origin main

# If using GitHub CLI
gh repo unarchive OWNER/REPO

# Check the README for migration notices
# Look in the repository description
# Check pinned issues or the wiki

# Common patterns:
# - "This project has moved to https://github.com/new-org/new-repo"
# - "Superseded by project-v2"
# - "Merged into monorepo at ..."

# For GitHub Actions that push tags/releases:
# You need to update the repository reference

# Example: Update workflow to push to a fork
- name: Push changes
  run: |
    git remote set-url origin https://github.com/YOUR-ORG/YOUR-FORK.git
    git push origin main

# Or skip the push step entirely if the repo is archived
- name: Push changes
  if: ${{ github.repository != 'archived-owner/archived-repo' }}
  run: git push origin main
