Chapter 1.1: Retrieving the image
|
|
|
|
|
=================================
|
|
|
|
|
|
|
|
|
|
Before you install Lubuntu, you need to retrieve the correct image. Lubuntu offers two different kinds of images,
|
|
|
|
|
Alternate and Desktop images. Lubuntu also provides support for many different CPU architectures. Lubuntu releases a
|
|
|
|
|
new version every six months (supported for nine (9) months), with every two years having a long term support release
|
|
|
|
|
(supported for three (3) or five (5) years, depending on the release).
|
|
|
|
|
|
|
|
|
|
Choosing between alternate and desktop
|
|
|
|
|
--------------------------------------
|
|
|
|
|
Alternate images are mainly intended for older, lower spec hardware and uses a non-graphical installer. The desktop
|
|
|
|
|
version offers a live session to try out Lubuntu and make sure all of your hardware works before you install it on
|
|
|
|
|
your computer. The installer on the desktop is a graphical installer where you can use a mouse and keyboard and it is
|
|
|
|
|
more user friendly, but this takes more resources than what is usually required to run Lubuntu itself, due to the
|
|
|
|
|
fact that the desktop image runs from your RAM while Lubuntu normally runs from your hard drive. If your computer has
|
|
|
|
|
less than 512 MB of RAM it is recommended to use the alternate installer as it will perform better with your system.
|
|
|
|
|
The alternate installer does not provide a live session so therefore it uses less RAM.
|
|
|
|
|
|
|
|
|
|
Lubuntu offers images for three different architectures:
|
|
|
|
|
- amd64 (commonly referred to as 64-bit)
|
|
|
|
|
- i386 (commonly referred to as 32-bit)
|
|
|
|
|
- PowerPC
|
|
|
|
|
|
|
|
|
|
amd64
|
|
|
|
|
------
|
|
|
|
|
The amd64 image will work with most modern processors. The best way to determine if your computer has an amd64 or
|
|
|
|
|
i386 processor is to boot the image. It's the only way that you will be able to know for sure what architecture your
|
|
|
|
|
computer is. amd64 computers are backwards compatible with i386 images. You may want to use an i386 image instead if
|
|
|
|
|
you have an amd64 processor with very low amounts of RAM.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
i386
|
|
|
|
|
----
|
|
|
|
|
This is the original 32-bit architecture that will work best on computers with very low amounts of RAM.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
PowerPC
|
|
|
|
|
-------
|
|
|
|
|
PowerPC is for older Macintosh hardware from before 2006 and IBM OpenPower systems. While we don't release PowerPC
|
|
|
|
|
for non-LTS releases (like 16.10), you can download a 16.04 image if you wish and upgrade it.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Ways to download the image
|
|
|
|
|
---------------------------
|
|
|
|
|
Now that the decision of which image type and architecture is done, you will need to download the image.
|
|
|
|
|
|
|
|
|
|
There are several ways to download the Lubuntu image:
|
|
|
|
|
- HTTP download (from your web browser or terminal)
|
|
|
|
|
- BitTorrent (from a BitTorrent client such as Transmission)
|
|
|
|
|
- zsync (from the terminal, recommended)
|
|
|
|
|
|
|
|
|
|
You can also download the image via Jigdo but we will not cover that in this manual.
