# 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
```yaml
- 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:
```bash
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:
```yaml
baseurl: "/AeThex-OS"
```
### Issue: Links broken
**Solution:** Use absolute paths from baseurl:
```markdown
[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:
```bash
git revert bf4ea61
git push origin main
```
Then investigate alternative solutions.
