How To Upgrade Webmin

Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.

Like any other piece of software on the market, there are occasionally security patches, bug fixes and feature upgrades available for upgrade. You can usually find these out on the Webmin homepage, or alternatively have your installed version of Webmin inform you about both minor (module-only) and major (full-upgrade) updates available custom tailored for your local configuration (do this by setting a Scheduled Upgrade in the Webmin Configurtion --> Update Webmin and having it not really perform the upgrade, but just inform you of available upgrades - it will send the upgrade information to root at your system).

Luckily Webmin has a built-in upgrade and configuration mechanism to make this task a piece of cake!

To start, let's click on Webmin in the main menu and select "Webmin Configuration". We'll start by ensuring that Webmin is up-to-date, by selecting "Upgrade Webmin". In the following screen select "Latest version from www.webmin.com" check "Upgrade even if" and then click the "Upgrade Webmin" button.

This will check the latest version and upgrade the version installed on your machine - it may take time to download the upgrade, so be patient. Once it finishes, it may offer to install updates for your new version of Webmin. You're encouraged to click where prompted and install those too.
