There is an easier way to install Webmin on Ubuntu 12.04 LTS! This walkthrough shows how to install Webmin 1.580 and upgrade the TLS self-signed certificate to use a 2048-bit key.
I had some trouble installing Webmin 1.510 on Ubuntu 10.04 LTS Server (aka Lucid). The problem is that Webmin uses a deprecated Perl module (a wrapper around Digest::MD5 for users of an ancient MD5 library) and both Debian and Ubuntu refuse to put it back into their respective repositories. Entirely within their rights, of course, but not so good for us weekend admins who want a painless install process.
Okay, so let’s get to work. I’m installing Webmin 1.510 via the remaining Debian packages.
Install the (easy) dependencies
Run this from a terminal. Expect some trouble from ‘libmd5-perl’.
$ sudo aptitude -y install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl apt-show-versions libapt-pkg-perl
You should find an error like this:
Couldn't find any package whose name or description matched "libmd5-perl"
The reason for this is that ‘libmd5-perl’ is persona non grata at both Debian and Ubuntu, as mentioned.
Install the deprecated dependencies
Download the libmd5-perl deb file and install it manually:
Open a browser and get the newest libmd5-perl package (from 2004 – lol)
The likely package is named: libmd5-perl_2.03-1_all.deb
so we download it and install it:

The dependencies should all be installed now. We can download the Webmin deb package from Sourceforge.
Use the most recent deb package. In my case it was ‘webmin_1.510-2_all.deb‘
Sourceforge will generate a link for you to use from their web site. My link was:

You should now be able to visit your webmin login page on port 10000 (use your own IP number):
Ideally, the Webmin gurus will refactor the old MD5 code dependencies, but this seems to work fine for now.
