Before you install Lubuntu, you need to retrieve the correct image. Lubuntu supports AMD64 CPU types also known as 64-bit with a new version every six months (supported for nine months), and every two years being a long term support release (supported for three years). If you have a 32 bit processor we unfortunately had to drop support but 18.04 LTS is still supported until 2021 for 32 bit. Lubuntu 20.04 is a Long Term Support release supported until 2023.
Lubuntu offers two types of releases. The **Long Term Support** release, or the **LTS**, is the release recommended for most users. It is supported for three years after the release date and does not contain new features. Throughout the course of the cycle, the Ubuntu Kernel Team will deliver **Hardware Enablement** updates, or **HWE** updates, to Lubuntu via Linux kernel updates. Previously, Lubuntu used **LXDE** but since 18.10 it has used the **LXQt**. Lubuntu 20.04 is the First **Long Term Support** release which uses the more modern **LXQt** desktop environment.
For users looking to try new features every six months at the expense of the support cycle length, Lubuntu offers **interim releases**, or **regular releases**. These releases, while they are considered stable, are testing grounds for major, new features which will be rolled into the LTS release. Users of the regular releases are typically enthusiasts and somewhat more experienced users looking for a fresher experience.
**It is extremely important that if you choose this path, you upgrade to each successive regular release shortly after it comes out.** If you are not comfortable doing this, you should consider using the LTS release instead.
An easy download page which lists the HTTP and BitTorrent downloads is available `on the Lubuntu website's Downloads page <https://Lubuntu.me/downloads/>`_, however for zsync downloads, you need to visit `cdimage.ubuntu.com <http://cdimage.ubuntu.com/lubuntu/>`_, which has the files listed.
After you download the image, you **must** verify it, as this is the most common reason there are problems with a Lubuntu install. There is `a helpful page on the Ubuntu Community Help wiki <https://help.ubuntu.com/community/VerifyIsoHowto>`_ that can guide you in the right direction.
..warning:: Downloading via HTTP and not verifying the image can lead to hours of frustration with even the developers quite confused what is happening with your system. With just one bit of the image flipped will cause massive frustration and a failed install.
Instead of downloading the image from one server, you can "torrent" the image, or download it from multiple sources instead of just one. This is often faster and saves the bandwidth of the Ubuntu cdimage servers. If you would like to learn more about BitTorrent, take a look at `the Wikipedia page on the subject <https://en.wikipedia.org/wiki/BitTorrent>`_.
In order to torrent the file, you need a BitTorrent client. We recommend `Transmission <https://transmissionbt.com/>`_, an Open Source BitTorrent client. Since Transmission only provides clients for Linux and macOS, we recommend `qbittorrent <https://www.qbittorrent.org/download.php>`_ for Windows users.
After you have downloaded the link you need, open it in your BitTorrent client. This will download the image. After this is done, we recommend that you leave your BitTorrent client open so you can seed this image for other people, which helps reduce bandwidth costs even further by decentralizing the download location for other users.
zsync is a convenient application that will automatically verify the checksum of the image once downloaded. The Lubuntu team uses this to download daily images as it will seamlessly download the delta or difference since the last image was spun.
