How to go from Ubuntu to Lubuntu. All you need to know

From Ubuntu to LubuntuThe standard version of Ubuntu is a very complete operating system, but it must be recognized that it does not work equally well on all computers. If our computer has limited resources, Unity is not the best graphical environment that we could use. But what do we do if we have already installed Ubuntu on our PC, we want to use a light environment and we don't want to lose our data? In that case, it's best to use a lighter layout and it might be a good idea. move from Ubuntu to Lubuntu. In this guide we will teach you everything you need to know to get it

How to go from Ubuntu to Lubuntu without losing our data

Reinstalling the system

It would not be my preferred option, but it is not a bad option because it is the simplest. The process would be the following:

  1. We download the ISO image of Lubuntu. It is available from THIS LINK.
  2. If we don't have it installed, we install UNetbootin by opening a Terminal and typing the following command:
sudo apt-get install unetbootin
  1. Once installed, we launch it by typing "unetbootin" (without the quotes) in the Terminal.
  2. It will ask us for the password. We introduce it.
  3. In UNetbootin, we select the ISO that we have downloaded in step 1 and the Pendrive where we will record it. If we prefer, we can download Lubuntu directly from UNetbootin, but I prefer to do it from the official page that ensures that I download the latest version.
  4. We click OK and it will begin to record the image on the Pendrive.


  1. Next we start from the USB and we can follow the tutorial to install Lubuntu from THIS LINK, but in the type of installation we will choose "Reinstall Ubuntu". This will keep the files in our personal folder.

Reinstall Lubuntu

We also have another option that I like better, but it is necessary to carry out some previous steps. Is about create three partitions for our system, which can be added to other partitions if we also have Windows installed. The three partitions will be for the root, one for exchange and another for our personal folder. To create the partitions we can use the tool GParted. Once we have the three partitions, when installing the new system we will choose "More options".

More options when installing Lubuntu

When you finish calculating the space of each partition, we will see an image like the following:


As you can see, I have a lot of partitions, but because I also have Windows installed so that may happen. What we have to do if we choose this method is to look at the space of each partition. For example, if we have created a 100GB partition for our personal folder, we will have to find the 102.400 MB partition, click on «Change» and configure it as / Home. The first time it will be empty, but if we reinstall the system and do not format that partition, the files in our personal folder will be available when we finish installing the new system.

The same thing we have done with the personal folder we have to do it with the swap partition and with the root (/). The swap partition can be 1GB, it doesn't have to be very large. Choosing this method we will only save our documents and we will not carry any failure that we could have experienced.

Installing only the graphical environment of Lubuntu

But, if we want, we can also install only the graphical environment. There will be different ways to do it:

  • Installing the Lubuntu desktop without recommended applications, which we will do by opening a Terminal and typing the following command:
sudo apt-get install --no-install-recommends lubuntu-desktop
  • Installing entire Lubuntu desktop with the command:
sudo apt-get install lubuntu-desktop

From the Lubuntu Software Center we can eliminate the applications that we are not going to use. If we want, we can remove the Lubuntu Software Center (I don't recommend it) with the following command:

sudo apt-get remove lubuntu-software-center

As I have already mentioned, my favorite method is to create the partitions first and then install the system using the created partitions. That is the method I usually use and once we do it a couple of times it costs nothing. What do you think is the best way to go from Ubuntu to Lubuntu?

    I'd rather do it the other way around.

    Thank you very much for the information,
    It would be good if you could teach us newbies to go from 64 to 32 bits, because I see that the order is quite slow for me, the truth is that I was wrong to put 64 bits.
    A greeting.
