This article introduce some suggestions after installing elementary OS 0.4 Loki. They are including installing Firefox, LibreOffice, BitTorrent client, Inkscape and GIMP, and educational software. We write and made them easy to help complete beginners in GNU/Linux especially in elementary OS. We hope these suggestions really helpful for you.


About Multimedia Codecs


elementary OS Loki is already shipped with preinstalled all* multimedia codecs. For example, Loki is capable to play proprietary standard like mp4, mp4, flv; and also capable to play free/open standard like ogg, ogv, flac, and webm. As a comparison, it is complete opposite with Linux Mint 18 which is no longer shipping with proprietary/closed-format multimedia codecs.




*) The term "all" here refers to both free/open multimedia formats (such as ogg) and proprietary/closed formats (such as mp3). Multimedia codecs like Fluendo GStreamer framework is free software, not proprietary software.

1. Reload


One thing we need to do is synchronizing elementary OS system with the repository. This synchronization is part of elementary OS package management, represented with command line apt-get update. We simply call it reload*.

First, open Terminal (Super+T) > check your software sources by this command line > you must see the same output like the picture following. Just copy and paste this command into Terminal.

cat /etc/apt/sources.list | sed '/\#/d'
Second, in the same Terminal, perform this "Reload" command line. It costs around 38 MB:

sudo apt-get update

Note: once reload finished, you should see your AppCenter program shows full list of more than 50000 installable software packages. And you should able to search any software from command line apt-cache search <program_name>.

*) Reload (or actually apt-get update) is merely a process of downloading index files from the repository. It does not download or install any software package.

2. Change Repository


If you want to change location of your repository into your own country, or even your city, change it by looking at list of Ubuntu mirror repositories worldwide https://launchpad.net/ubuntu/+archivemirrors. For your information, elementary OS is derived from Ubuntu so it uses Ubuntu mirror  repositories directly.

First, examine your software sources first. There are three command lines for that, showing below as bolded lines in three separated blocks. They are lines of software sources URLs. What you need to change is only the first blocks.

master@master:~$ cat /etc/apt/sources.list | sed '/\#/d' | sed '/^$/d'
deb http://id.archive.ubuntu.com/ubuntu/ xenial main restricted
deb http://id.archive.ubuntu.com/ubuntu/ xenial-updates main restricted
deb http://id.archive.ubuntu.com/ubuntu/ xenial universe
deb http://id.archive.ubuntu.com/ubuntu/ xenial-updates universe
deb http://id.archive.ubuntu.com/ubuntu/ xenial multiverse
deb http://id.archive.ubuntu.com/ubuntu/ xenial-updates multiverse
deb http://id.archive.ubuntu.com/ubuntu/ xenial-backports main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu xenial-security main restricted
deb http://security.ubuntu.com/ubuntu xenial-security universe
deb http://security.ubuntu.com/ubuntu xenial-security multiverse

master@master:~$ cat /etc/apt/sources.list.d/elementary.list
deb http://ppa.launchpad.net/elementary-os/stable/ubuntu xenial main
deb-src http://ppa.launchpad.net/elementary-os/stable/ubuntu xenial main

master@master:~$ cat /etc/apt/sources.list.d/patches.list
deb http://ppa.launchpad.net/elementary-os/os-patches/ubuntu xenial main
deb-src http://ppa.launchpad.net/elementary-os/os-patches/ubuntu xenial main

Second, to change the repository location, edit the sources.list file above by Scratch text editor. Just replace the country code in every line into your country identifier. For example, replace "id." with "jp." for Japanese mirror, or replace "id." with "de." for Germany mirror, and so on. Follow command line and picture below.

sudo scratch-text-editor /etc/apt/sources.list

3. Upgrade


elementary OS provide complete upgrading service for whole the system and for all your installed software. If you would like to do upgrade, you can do it from AppCenter. Just view the tab Updates and click Update button.



But if you like console, do it in Terminal instead:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get upgrade-dist

4. Install Mozilla Firefox


Firefox is not installed by default, so you can install it yourself from AppCenter.



But if you prefer console, here is the command line:

sudo apt-get install firefox


5. Install LibreOffice


LibreOffice is not installed by default, so you can install it from AppCenter.



Or if you prefer console, choose one of command lines below:


# install the complete suite
sudo apt-get install libreoffice


#install only each component

sudo apt-get install libreoffice-writer
sudo apt-get install libreoffice-calc
sudo apt-get install libreoffice-impress
sudo apt-get install libreoffice-math
sudo apt-get install libreoffice-draw
sudo apt-get install libreoffice-base


6. Install BitTorrent Client


Any BitTorrent client is not installed by default. But there are so many BitTorrent software available in the repository. You may install either Transmission, Deluge, qBittorrent, or KTorrent, from AppCenter.



Or, if you like console, perform one of these command lines:

Transmission
sudo apt-get install transmission
Deluge
sudo apt-get install deluge
qBittorrent
sudo apt-get install qbittorrent
KTorrent
sudo apt-get install ktorrent

7. Change Dock Behavior

You can change bottom dock (Plank) behavior, either to hide or not to hide. Open System Settings > Desktop > Dock > slide off the Hide when option slider.


You can also change that Plank hiding behavior, by slide on the slider and choose one the these options:




8. Arrange Desktop Icons


elementary OS has no desktop shortcuts icon like in Microsoft Windows desktop (also, it has no right-click on desktop). But elementary OS has bottom dock called Plank. You place your icons there.




  • To add an icon to dock, for example: open desktop menu > right-click Files icon > Add to Dock
  • To remove an icon from dock, for example: right-clik an icon > uncheck "Keep in Dock" checkbox.

9. Install Desktop Software


elementary OS Loki doesn't ship with common desktop software like Inkscape and GIMP. They are installable from AppCenter.



Here are command lines to install some of them.


Inkscape
sudo apt-get install inkscape

GIMP
sudo apt-get install gimp

Shutter
sudo apt-get install shutter

Scribus
sudo apt-get install scribus


10. Install Education Software


elementary OS is suitable for educational purposes, and it provides so many educational software starting for children until university level. For example, there are GCompris for kids, Marble and KGeography for geographical learning and teaching, Kig and KAlgebra for mathematics, Kalzium for chemistry, and so on. They are installable via AppCenter.


Here are command lines to install some of them.


GCompris
sudo apt-get install gcompris

Kalzium
sudo apt-get install kalzium

Dr. Geo

sudo apt-get instal drgeo

11. Install Communication Software


elementary OS doesn't ship with any IRC client and instant messaging program. You have many choices among them, for example HexChat for IRC and Pidgin for instant messaging. You can install them from AppCenter, or, at your option, from console.



Here are command lines to install some communication software.

Pidgin
sudo apt-get install pidgin

HexChat
sudo apt-get install hexchat
