Webmin installation on Ubuntu 22.04

No matter how hard core cli user you are it very often that you will need a GUI to perform some tasks just because, you can’t remember the commands or you want a better visualization (Firewall ports comes to mind).

I know some prefer Cockpit but I vote for Webmin. Here is how to install in on Ubuntu 22.04

SSH to your server, get root privileges and update the package indexes.

sudo su

apt update

In order for your installation to trust the Webmin repository you need to install the PGP key and convert it to a format that apt can use to verify the files

curl -fsSL https://download.webmin.com/jcameron-key.asc | sudo gpg --dearmor -o /usr/share/keyrings/webmin.gpg

Edit the repositories list

nano /etc/apt/sources.list

Scroll all the way to the end of the file and add

deb [signed-by=/usr/share/keyrings/webmin.gpg] http://download.webmin.com/download/repository sarge contrib

Save and Exit

Update the repositories and install webmin

apt update

apt install webmin

Now you can access the GUI interface by
