Troubleshooting

Common Issues

Permission Denied:

# Ensure script has execute permissions
chmod +x updater.sh

# Run with sudo
sudo ./updater.sh [paths]

PHP Version Too Old:

# Script will prompt to auto-upgrade PHP
# Or manually upgrade PHP first:
sudo apt-get update
sudo apt-get install php8.3

Download Failures:

# Check internet connection
curl -I https://github.com

# Verify GitHub access
curl -s https://api.github.com/repos/moodle/moodle/tags | head

Database Backup Issues:

# Ensure database tools are installed
sudo apt-get install mysql-client    # For MySQL/MariaDB
sudo apt-get install postgresql-client  # For PostgreSQL

# Verify database credentials in config.php

Debug Mode

The script automatically enables debug mode during updates. To manually enable:

// In config.php
$CFG->debug = 32767;
$CFG->debugdisplay = 1;
