Select the options for Ubuntu Focal (20.04 LTS) (long term support) and HAProxy 2.4-stable (LTS). At the time of this writing, the latest version was 2.4. Head over to, where you can select the install instructions for your OS. Everything we do here should work equally well on bare metal or any cloud provider. For testing, I’m using a virtual machine running on my laptop. In the case of HAProxy, which is already provided by the official sources, once the PPA is installed, apt will use this custom package over the default.
A custom PPA tells Ubuntu to use a software source outside its normal channels and install a custom package. Fortunately, Vincent Bernat has done all of the hard work and released something called a PPA, or Personal Package Archive. You can compile the source code yourself, but that can be a lot of extra steps. The version you get with apt out-of-the-box will be stable and secure, but it’s going to lack some of the cool new features you’ve been reading about, such as FIX protocol support, HTTP/2 WebSockets, or Dynamic SSL Certificate Storage. Yes, that simple command will quickly and easily set you up with HAProxy, but you’ll find that the version you’ve just installed probably lags behind the current release by a minor version number or two, sometimes as much as a major version number. It’s so easy that installing HAProxy on a brand new Ubuntu box can be as simple as a one-line apt command: apt lets you easily install and remove packages and dependencies, generally without having to worry about the nitty-gritty details of file paths, libraries, compilers, and version conflicts.
One of the features that makes Ubuntu so accessible to even the newest of users is its package manager, apt, the Advanced Packaging Tool. It’s a free Linux operating system that’s fast, secure, and best of all, it’s easy to use. Ubuntu 20.04 is a great choice for installing your HAProxy software load balancer.
