By default, for an individual, when he connects to the Internet, the DNS server addresses provided in DHCP are those of his Internet service provider. But it is possible to choose others. Here is how to change DNS server in Ubuntu (18.04 and 20.04). Prerequisites Have Ubuntu 16.04 or higher Introduction to DNS What is a DNS server? DNS is the abbreviation for Domain Name System. A DNS server is a system whose purpose is to convert an Internet address (www.domainname.ext) into an IP address (physical address of machines connected to a network). This is called domain name resolution. So, for example when you type in your browser www.wikipedia.fr, the DNS server converts the path to the IP address: 78.109.84.114. You can find out this IP address by pinging the domain. For example : ping wikipedia.fr and under Linux you will have an answer of this type PING wikipedia.fr (78.109.84.114) 56 (84) bytes of data. 64 bytes from wikimedia2.typhon.net (78.109.84.114): icmp_seq = 1 ttl = 51 time = ...

Several methods are possible to set up a network share in Ubuntu (and its official variants Xubuntu, Kubuntu, Lubuntu, ...) in order to easily exchange files with other computers on the same network. Here we will see how to do it with the Samba protocol. Introduction Several protocols allow you to share folders on a local network. The two main ones are: SMB (Server Message Block): originally on Windows with the old name CIFS (Common Internet File System). Samba is its open-source version for Linux systems. NFS (Network File System): initially intended for Unix systems (including Linux), but also available for Windows or Mac. In this tutorial, we will be using Samba to create a network share in Linux Mint. Indeed, this protocol has several advantages: most OS (hence Ubuntu) support access to shared resources through the latter. Setting up a network share in Ubuntu via Samba is easy once the additional packages are installed. Install Samba to create network shares in Ubuntu As said befor...

Your Interface is in the wrong language or translations are missing. Here is a tutorial to change the language of Linux Mint (to French for example) or install some of the missing translations. Introduction What is software regionalization Put simply, the regionalization of a software corresponds to the translation of the user interface in a language other than the default one as well as the formatting of numbers, dates, measures, etc. in the sauce of the chosen locality. But, not all software necessarily has translation and / or regionalization ... The global regionalization of Linux Mint It is done during the first step of installing Linux Mint with the choice of language. This choice allows: to have a guide in French (or other) for the following steps and above all to finally have the system and basic applications in the selected language. Except that some of the language installation packages must be downloaded in order to install them. So if you don't have an internet connecti...

Your Interface is not in your language or translations are missing. Here is a tutorial to change the language of Ubuntu (to switch to French for example…), install some of the missing translations and change the region. Prerequisite Be on Ubuntu 18.04 or higher Have an account with administrator rights Have an internet connection. It is needed to download and install language packs from Ubuntu repositories. Introduction What is software regionalization Put simply, the regionalization (or localization) of a software corresponds to the translation of its interface into a language other than the default one as well as the formatting of numbers, dates, measures, etc. depending on the location chosen. But, not all software necessarily has translation and / or regionalization ... The global regionalization of Ubuntu It is done during the first step of installing Ubuntu with the choice of language. This choice allows: to have the installation guide in French (or other) and above all to finall...

By default, Linux Mint does not support the Snap format and application installation from Snap Store. Also, here's how to change that on Linux Mint 18.x, Linux Mint 19.x, and Linux Mint 20. Introduction What is Snap? Snap is a package management system offered by Canonical (developers of Ubuntu). One of its goals is to allow developers to provide, for an application, a single installer (a Snap package) that can be installed on any distribution regardless of its version and state. Indeed, all dependencies must be included in the package and the application will be executed in a sandbox which will isolate it from the system and strengthen security. Packages are centralized and distributed from a single app store: the Snap Store. The clients (what we install on our system) are under a free license (GPLv3), but not the server that hosts and distributes the packages to be installed ... Initially only supported in Ubuntu (and for good reason ...), it is also possible to use it with other...

Debian offers on its repositories and installs by default only Firefox ESR. Firefox ESR (Extended Support Release) is a version of the Mozilla browser with greater stability than the “normal” version of the browser. Its major versions (with the addition of new features) are only released once a year, while the normal version has several each year. But it has extensive support that covers the period between two releases plus a few extra weeks. But, it is possible to have the normal version of Firefox on Debian. Here are two ways to have it. Method 1: Install the standard version of Firefox on Debian with Flatpak In my opinion, this is a simple solution to install the standard version of Firefox on Debian since Firefox is available as Flatpak on the Flathub. But, some extensions communicating with other applications (keepassxc-browser, kee, ...) may no longer work. For those who do not know, Flatpak is an independent system for the secure and easy management and distribution of Linux app...

Here I offer two easy methods to directly install the latest version of Skype on Debian. These methods all allow you to keep your version of Skype up to date in the future. They all have their advantages, so none is better than the other. It is up to you to make your choice. Prerequisite Have a 64-bit version of Dedian. For those with 32 Bits, it is possible to use Skype Web from the Chromium browser (not compatible with Firefox ESR). To find out its architecture (32 or 64 bits), open a terminal and do: uname -m if in response you have x86_64, your system is 64 bit. But if it's i686 or i386, it's 32 bit. So not compatible for Skype… uname -m on Debian 64 bits Method 1: Install Skype on Debian in Debian Format Debian does not offer any Debian package for Skype from its official repositories. Normal, Skype is proprietary software of Microsoft. But the latter offers a repository to install and update Skype which it maintains directly. In fact, the Skype installer, downloadable fro...
