GitHub Pages 404 Fix - Applied ✅

Problem

GitHub Pages was deploying but showing 404 errors. The GitHub Actions logs showed only the "deploy" job running, not the "build" job.

Root Cause

The workflow was using actions/jekyll-build-pages@v1 which requires specific setup, but wasn't properly building the Jekyll site before deployment.

Solution Applied

1. Updated Workflow (.github/workflows/pages.yml)

Changed from: Using actions/jekyll-build-pages@v1 (pre-built action)
Changed to: Manual Jekyll build with proper Ruby setup

- name: Setup Ruby
  uses: ruby/setup-ruby@v1
  with:
    ruby-version: '3.1'
    bundler-cache: true

- name: Build with Jekyll
  run: bundle exec jekyll build --baseurl "${{ steps.pages.outputs.base_path }}"
  env:
    JEKYLL_ENV: production

2. Added Gemfile

Created Gemfile with GitHub Pages dependencies:

• github-pages gem (includes Jekyll and plugins)
• jekyll-seo-tag, jekyll-sitemap, jekyll-feed
• kramdown-parser-gfm (for GitHub Flavored Markdown)
• webrick (required for Ruby 3.0+)

3. Updated .gitignore

Added Jekyll-specific ignores:

/.bundle/
/vendor/
/_site/
/.jekyll-cache/
/.jekyll-metadata
Gemfile.lock

Verification Steps

1. Check GitHub Actions:

   • Go to: https://github.com/AeThex-Corporation/AeThex-OS/actions
   • Latest workflow should show both "build" and "deploy" jobs (green)

2. Wait for Deployment:

   • Full build takes ~2-3 minutes
   • Watch for "Deploy to GitHub Pages" completion

3. Visit Your Site:

   https://aethex-corporation.github.io/AeThex-OS/
   

4. Test Documentation Hub:

   https://aethex-corporation.github.io/AeThex-OS/docs/
   

5. Test OS Specification:

   https://aethex-corporation.github.io/AeThex-OS/docs/AETHEX_OS_SPECIFICATION
   

Expected Build Output

You should now see in GitHub Actions logs:

✅ Checkout
✅ Setup Ruby
✅ Setup Pages
✅ Build with Jekyll
   - Configuration file: _config.yml
   - Source: /home/runner/work/AeThex-OS/AeThex-OS
   - Destination: /home/runner/work/AeThex-OS/AeThex-OS/_site
   - Generating...
   - Jekyll Feed: Generating feed for posts
   - done in X.XX seconds.
✅ Upload artifact
✅ Deploy to GitHub Pages

Common Issues & Solutions

Issue: Still getting 404

Solution: Clear browser cache or try incognito mode

Issue: Build job fails with Ruby errors

Solution: Check Gemfile.lock was generated properly. If not:

bundle install
git add Gemfile.lock
git commit -m "chore: Add Gemfile.lock"
git push

Issue: CSS/assets not loading

Solution: Verify baseurl in _config.yml matches repo name:

baseurl: "/AeThex-OS"

Issue: Links broken

Solution: Use absolute paths from baseurl:

[Link](/AeThex-OS/docs/page)

Files Modified/Created

Created:

• ✅ Gemfile - Jekyll dependencies
• ✅ docs/GITHUB_PAGES_404_FIX.md - This troubleshooting guide

Modified:

• ✅ .github/workflows/pages.yml - Fixed build process
• ✅ .gitignore - Added Jekyll ignores

Next Steps

1. Monitor the build at: https://github.com/AeThex-Corporation/AeThex-OS/actions
2. Wait 2-3 minutes for complete deployment
3. Visit site to confirm it works
4. If still 404, check:
   • GitHub Pages is enabled in Settings → Pages
   • Source is set to "GitHub Actions"
   • Build completed successfully (green checkmark)

Technical Details

Why the Original Workflow Failed

actions/jekyll-build-pages@v1 expects a specific setup:

• Minimal config in _config.yml
• No Gemfile or only specific gems
• Standard Jekyll directory structure

Our project has:

• Custom theme configuration
• Multiple collections
• Complex navigation
• Root-level markdown files

Why the New Workflow Works

• Explicit Ruby setup with version control
• Manual Jekyll build with full control
• Proper baseurl injection from GitHub Pages
• Bundle caching for faster builds
• Production environment variable set

Rollback (If Needed)

If this causes issues, revert with:

git revert bf4ea61
git push origin main

Then investigate alternative solutions.
