Avidemux video editor

Avidemux video editor reached the new 2.7 series a few days ago. Now you can install it in Ubuntu 16.04 and/or Ubuntu 17.04 via GetDeb repository, though there’s already an appimage available.

For the release highlights and appimage, a single executable file (non-install), see this page.

To install Avidemux 2.7, open terminal via Ctrl+Alt+T or by searching for “terminal” from app launcher, and do following steps:

Avidemux 2.7.0

1. Add the GetDeb repository via command:

sudo sh -c 'echo "deb $(lsb_release -sc)-getdeb apps" >> /etc/apt/sources.list.d/getdeb.list'

For Linux Mint 18.x, replace $(lsb_release -sc) directly with xenial in the command. Type in your password when prompts and hit Enter.

2. Download and install the repository key via command:

wget -q -O - | sudo apt-key add -

3. Finally install avidemux2.6-qt either via Synaptic Package Manager:

avidemux 2.7 via synaptic

or by running command:

sudo apt-get update

sudo apt-get install avidemux2.6-qt

It’s Avidemux 2.7 though getdeb still uses the old 2.6 package naming system.


You can remove the GetDeb repository via Software & Updates utility (Other Software tab), and remove Avidemux 2.7 either via Synaptic package manage or by running command:

sudo apt-get remove --autoremove avidemux2.6-qt

Gnome Twitch App

Gnome Twitch, GTK+3 Twitch app for Linux desktop, now is available as Snap package in beta channel for testing.

WebUpd8 PPA is maintaining the latest Gnome Twitch app for Ubuntu, however, Ubuntu 16.04 LTS is excluded due to old system GTK+3 libraries.

Now Ubuntu 16.04 and even Ubuntu 14.04 users can easily install the latest Gnome Twitch app via snappy store, though it’s in beta stage at the moment.

1. For those who’ve never installed a snap app, install the snapd deamon first in terminal (Ctrl+Alt+T):

sudo apt install snapd snapd-xdg-open

Input your password (no visual feedback while typing due to security reason) when it prompts and hit Enter.

2. Install Gnome Twitch snap app via command:

sudo snap install --beta gnome-twitch

3. And gnome environment is required. Install and connect to it via 2 commands:

sudo snap install gnome-3-24

sudo snap connect gnome-twitch:gnome-3-24-platform gnome-3-24:gnome-3-24-platform

Finally launch the app from your application launcher and enjoy! And it should automatically update itself once a new release is out and published in snappy store.


To remove Gnome Twitch snap app, simply run command:

sudo snap remove gnome-twitch

You may also remove the gnome-3-24 snap if you don’t require it via sudo snap remove gnome-3-24 command.

fre:ac audio converter

This quick tutorial is going to show you how to install the free ‘fre:ac’ audio converter in Ubuntu and manually create app shortcut to be able to launch it from Unity Dash, Gnome app launcher, or other app launcher.

fre:ac is a free audio converter and CD ripper works on Windows, Mac OS, Linux, and FreeBSD. It offers Linux packages but lacks application shortcut.

Download fre:ac:

First download the latest version of the audio converter from the link below:

Download fre:ac for Linux

Select download:

  • freac-yymmdd-linux.tar.gz package for 32-bit system.
  • freac-yymmdd-linux-x64.tar.gz package for 64-bit system.

Then extract it. In the case below, I downloaded the 64-bit tarball:

You can now launch the audio converter by run the executable file from its context menu:

Create app shortcut for fre:ac audio converter:

To be able to launch the software from Unity Dash, Gnome app launcher, or other app launcher, you have to manually create an app shortcut for fre:ac.

To do so, open terminal via Ctrl+Alt+T or from app launcher, and do following steps:

1. Move the source folder to /opt/ directory for global use by running command:

sudo mv ~/Downloads/freac-*-linux /opt/freac-linux

Input your password (no visual feedback while typing due to security reason) when it asks and hit Enter.

Then change the ownship via command:

sudo chown -R root:root /opt/freac-linux

2. Create a symbolic link to the executable file, so you can easily run command freac to launch the software:

sudo ln -s /opt/freac-linux/freac /usr/bin/freac

3. Finally run command to create and edit a .desktop file for the audio converter:

gksudo gedit /usr/share/applications/freac.desktop

And paste below lines into the file and save it.

[Desktop Entry]
GenericName=freac audio converter
Comment=fre:ac free audio converter
Exec=env LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/freac-linux/ freac %f

It’s important to add variable env LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/freac-linux/ to the value of Exec, or it won’t launch the software and output error:

freac: error while loading shared libraries: cannot open shared object file: No such file or directory

4. Finally launch fre:ac audio converter from app launcher (might need log out and back in) and enjoy!

How to Remove:

To remove fre:ac audio converter, simply remove the source folder, symbolic link, and app shortcut by running following command:

sudo rm -rf /opt/freac-linux /usr/bin/freac /usr/share/applications/freac.desktop
