Kubuntu 18.04 Installation Guide

Kubuntu 18.04LTS

En this new release of Kubuntu 18.04 which it is renewed with Firefox 59 as a web browser, LibreOffice 6.0 as an office suite, Kirta 4.0.1 on the image editing side and several of the KDE desktop environment tools like kio-gdrive, Kstars, KDEConnect among others.

This time I share with you this little installation guide focused mainly on new users. Although Kubuntu is a derivative of Ubuntu, Kubuntu continues to support 32-bit systems so it is still an excellent option for those who want to continue with Ubuntu and do not want to use distributions that sacrifice the part of visual appearance.

El The first requirement to install Kubuntu 18.04 LTS is to download the ISO of the system for this it is extremely important to know if we also have the minimum requirements to be able to install the system and not have functionality problems.

To download the ISO we do it from its official site that you find it in this link.

Minimum requirements

To install Kubuntu 18.04 We must have at least the following requirements:

  • Processor: 1 GHz x86.
  • RAM memory: 1 GB.
  • Hard Drive: 10 GB for a full installation with swap included
  • VGA graphics card and monitor capable of supporting a resolution of 1024 × 768.
  • CD-ROM or network card reader.
  • Sound card.
  • Internet connection.

Prepare Installation Media

Windows: We can burn ISO with Imgburn, UltraISO, Nero or any other program even without them in Windows 7 and later it gives us the option to right click on the ISO.

Linux: You can use any CD image management tool, especially the one that comes with graphical environments, among them are, Brasero, k3b, and Xfburn.

Kubuntu 18.04 LTS USB Installation Media

Windows: You can use Universal USB Installer or LinuxLive USB Creator, both are easy to use.

Linux: The recommended option is to use the dd command.

dd bs=4M if=/ruta/a/Kubuntu.iso of=/dev/sdx sync

Kubuntu 18.04 LTS installation step by step

Before starting with the Kubuntu boot, we must configure the BIOS of our computer so that it starts with our installation medium, in addition to that if it has UEFI you must deactivate it, for those who do not know what UEFI is they can look a little in the net.

Once the system is booted, we will be inside it and a screen similar to the one I show will appear, where we will see a single icon on the desktop, we just have to double click this to start the installer wizard.

With that The wizard will start and immediately the first part of the configuration will be to choose the language With which we are going to work with the installer and the one that our system will have once it is installed and selected, click on next.

Now In the next step, it asks us if we want the installation to be done normally with all Kubuntu applications and configurations or if we want a minimal installation, this installation only includes what is necessary, which are necessary configurations and the web browser, everything else is discarded.

At the bottom it asks us if we want to install the private drivers as well as the updates of the system while the installation is carried out on our equipment.

In the next section we have to configure the space where Kubuntu 18.04 will be installed on our computer. Here we have two options.

  • The first is to remove everything from the disk and have the system installed on the entire disk.
  • The other one, which is the «Manual» one, in it we will configure the disk where we want it to be installed or the partition that we will assign to the system on our computer, here we can also edit the partitions to assign the swap if required and also an advanced installation separating the partitions to our need.

Done this, on the next screen we just choose our time zone.

Y finally we only configure a user, as well as a password for the system with which we will log in to it and it will be the one we use to use superuser privileges.

We just have to wait for the installation of Kubuntu 18.04 on our computer to finish, at the end we just have to remove our installation medium and restart our computer.

    Hi there! very good explanation! I want to install this operating system on my old notebook that has win vista, just one question I have, can I use a 4 gb pen drive?

    1.    David yeshael said

      Yes, the approximate weight of the ISO is 1.7 GB

  2.   Edwin said

    Excellent article, I tried the live CD and it runs fine, but when I install the main menu it only appears for half a second and disappears and I can't choose anything. What could be the reason?

    Among the minimum requirements for its installation you put what it must have: CD-ROM reader or network card.

    My pc does not have any of it but I do not understand why it is necessary for its installation, with a USB where you record the image and start from the serious enough, right?


    1.    David naranjo said

      The minimums are indicated, that is, what is essential to be able to carry out an installation and operation of the system.

    Some questions
    I want to install it on a pc that comes as OS, Endless OS, if I choose the guided option: use the whole disk, it will format me and I will only keep kubuntu as the operating system?

    If I choose the manual option, I can also assign all the space to kubuntu?

    And as for swap, the pc brings me 4 gb of ram, what size would it be advisable to assign swap or the default?

    1.    Baphomet said

      You can perfectly share the hard drive between the two systems. Having a swap greater than 1GB on a PC with more than 2GB of RAM is silly.

    It won't let me install it, error 5 (input) always appears, and it won't install, I've already formatted my entire pc, thinking that it may be the hard drive, and the memory (sd card) I can't blame it, since , I used it to install windows without any problem

    1.    Baphomet said

      Usually this happens because of one of three problems:
      1- Your hard drive has bad sectors, you can check / repair it by GNU / Linux with the command fsck -c / dev / sdxX (x - disk, X - partition) or by Windows CMD with chkdsk c: / f / r
      2- The ISO image that you copied does not work, you can check it with the md5sum or download it directly from http://cdimage.ubuntu.com/kubuntu/releases/.
      3- The SATA cable or the RAM memory may be dirty and / or deteriorated.

      1.    Baphomet said

        I meant that the RAM memory is dirty or damaged and / or the hard disk is connected to the first SATA (SATA 0) when it should be after the reader (if you are installing by a reader).

    The screen comes out with unreadable scratches.
