Guides

Practical step-by-step instructions for developers and system administrators — installation, maintenance, PHP, projects and troubleshooting.

System & maintenance

Basic Ubuntu system update

Updating OS packages via the panel or SSH — security patches and kernel maintenance.

Via the panel

System maintenance → Select apt update/upgrade action. The panel runs the task in the background and shows the log.
SSH (manual)

Take a VM snapshot before upgrading. After upgrade check if a reboot is required.
```
sudo apt update
sudo apt upgrade -y
[ -f /var/run/reboot-required ] && cat /var/run/reboot-required
```
Tip
Schedule reboots in a maintenance window — web projects will be briefly unavailable.
Post-update check

Check service status (Nginx, Apache, PHP-FPM, MariaDB) in the panel or recovery tools.
```
sudo /usr/local/uadmin/bin/recovery-stack.sh status
```
