sudo wget -q http://www.webmin.com/jcameron-key.asc -O- | sudo apt-key add -
2. Manually add the Webmin repository using:
sudo add-apt-repository "deb [arch=amd64] http://download.webmin.com/download/repository sarge contrib"

sudo ufw allow 10000/tcp
2. Reload your firewall for the changes to take effect:
sudo ufw reload
Note: The firewall is disabled on Ubuntu by default. If your system’s firewall is disabled, enable it with sudo ufw enable.

1. Set the password for the Webmin root user with:
sudo /usr/share/webmin/changepass.pl /etc/webmin root [new password]Note: Setting up a new password this way only works for existing users. You can’t use this method to set up new users.
2. Open your Internet browser and enter the following as a web address using your server’s IP:
https://[your server's IP]:10000/You can use local or remote server’s IP address.
Note: If you still haven’t set up a server for Webmin to manage, PhoenixNAP offers a choice of Bare Metal Cloud servers featuring high availability and performance. Start setting up your servers for as little as $0.10/hour!
3. Webmin generates its own SSL certificate not recognized by the browser, which causes a page indicating a potential security risk the first time you try to log in.
To get through this page, click Advanced…, then Accept the Risk and Continue.
4. Log in using the default username root and the password you set up.
5. Use the Webmin dashboard to review your system information.
