A Beginner's Tip for Manually Upgrading CyberPanel

The CyberPanel official website only provides a single command when introducing how to manually upgrade the system version, and I ran into several error prompts when following it step by step, including:

• rm: cannot remove ‘/usr/local/cyberpanel_upgrade.sh’: Permission denied
• chmod: changing permissions of ‘/usr/local/cyberpanel_upgrade.sh’: Operation not permitted
• /dev/fd/63: 8: /dev/fd/63: /usr/local/cyberpanel_upgrade.sh: Permission denied

The solution is actually very simple: you just need to first obtain the highest operating system privilege (root) to run the upgrade program smoothly, so simply execute the following upgrade commands in order to smoothly upgrade the CyberPanel version.

CyberPanel Upgrade Commands

1. sudo su -
2. sh <(curl https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh || wget -O – https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh)

The purpose of command one is to let the Linux user obtain root privileges; command two is the CyberPanel upgrade command, which will automatically upgrade to the latest version (if asked during the process, just press the confirm key (Enter));

If you plan to upgrade to another version, you can refer to the description about “Upgrading CyberPanel to a specific version” in the official website article “Upgrading CyberPanel”.
