How to install  * on Ubuntu and derivatives

This is a list of software installation sources and how to install them in the best conditions possible.

Many softwares are now available as snaps, flatpak or deb depots but some trouble can happen.

  • Sometimes, you want to install this software you love but the functionality you need was implemented in 1.x and the only one version available in official depots is 1.0.
  • Sometimes the Snap need a command to be installed | have the rights to access USB keys or a mounted NTFS file system.
  • Sometimes, the software is only available as an AppImage

Command line are “Plug-and-Play”. Just open the Terminal application and right-click → copy the command, right-click → paste it in the terminal. Press enter and type your password if the system asks. It’s invisible so don’t be surprised if you don’t see what you’re typing 😉

Non-free Video Codecs and Fonts

Reminder : these packages can be illegal in some countries (not france, Québec (Canada), Switzerland, Belgium,…) where software patents are valid. If you are in such a sh*** country, You have to pay for licences like this cra*

If you want to use some non-free audio/video formats or the window’s fonts, just type :

sudo install -y ubuntu-restricted-extras

You will have to accept the fonts licence. Move with arrow keys or TAB and press enter to press the “button”.


“This PPA version is a disaster !” If anything happends with a PPA, don’t worry just install (if you don’t already have it) :

sudo apt install -y ppa-purge

Now you can use it to remove any ppa with it’s content and replace anything that was changed with official versions !
Example :

sudo ppa-purge ppa:graphics-drivers/ppa

Add flatpak to Ubuntu

To add flatpak support to Ubuntu and it’s “Ubuntu Software”  :

sudo apt install -y flatpak gnome-software-plugin-flatpak && flatpak remote-add --if-not-exists flathub && flatpak update

With this, you have Flatpak integration and the main apps repository. Of course, there can be some private ones, but most of them are available here.


Thunderbird and symbols fix

Thunderbird comes with Ubuntu but if you installed a minimal version you can still add it with :

sudo apt install -y thunderbird

if you are experiencing some weird-sized icons / emojis troubles, here is a simple fix :

sudo apt install -y fonts-symbola



Select your distribution and click Download. Once downloaded, if installation process doesn’t start by itself, double-click the file or sudo dpkg -i megasync-xUbuntu_18.04_amd64.deb .

If  your distribution is using Gnome desktop or at least Nautilus as a files browser, you can click on “Nautilus extension” to download this really nice plugin for Nautilus.

It allows you to right-click on a file | folder → MEGA → Upload and put it anywhere you want on your Mega drive (sorry couldn’t resist, Europeans will understand 😝)


Make sure you have gconf. sudo apt install -y libgconf-2-4

Download the application from .

Right-click on the file → properties → security | authorizations and check the options allowing this to execute like a software.

or : chmod +x molotov.AppImage

Now you can double-click it.
