Installing Webmin on Ubuntu 16.04 LTS (Xenial Xerus)

The instructions how to install Webmin on Debian (and thereby also Ubuntu) seem a bit outdated because edits to the file /etc/apt/sources.list should be replaced by adding a file to the directory /etc/apt/sources.list.d/.

So, instead of adding

deb sarge contrib

to the file


create a new file


with that content and possibly a comment why you added it.

The rest seems to be up to date:

“You should also fetch and install my GPG key with which the repository is signed, with the commands:”

cd /root
apt-key add jcameron-key.asc

“You will now be able to install with the commands:”

apt-get update
apt-get install apt-transport-https
apt-get install webmin

“All dependencies should be resolved automatically.”

The reason why I installed Webmin was that updating a server from Ubuntu 14.04 to 16.04 broke the Webmin installation. I kept getting the error “module proc does not exist”. Google did not turn up anything useful for this so I decided to simply uninstall Webmin:

apt remove webmin
apt autoremove

And then I reinstalled it with the procedure described above. The error went away. I also got a new UI which will take a while to get used to.
