Audacity audio editor 2.4.x was missing from the unofficial PPA for a few months, due to build system change and my poor debian packaging skill.

Since the upstream maintainer has built the 2.4.2 package for Debian unstable and Ubuntu 20.10, backports for Ubuntu 20.04 and Ubuntu 18.04 now are here for you!

How to Install Audacity 2.4.2 via PPA in Ubuntu 20.04:

1.) Run command in terminal to add the PPA repository:

sudo add-apt-repository ppa:ubuntuhandbook1/audacity

Type user password (no asterisk feedback due to security reason) when it prompts and hit Enter to continue.

2. If you have a previous version installed, you can upgrade Audacity via Software Updater after adding the PPA.

or run following commands one by one to check updates and install (or upgrade) audacity 2.4.2:

sudo apt update

sudo apt install audacity

Uninstall:

To remove the PPA repository, launch Software & Updates utility and navigate to ‘Other Software’ tab. Or simply run command in terminal:

Gcolor3 – A GTK+ 3 Color Selector and Picker for Linux

Last updated: April 24, 2024

Gcolor3 is a color selector and picker written in GTK+ 3. It is much alike Gcolor2, but uses the newer GTK+ version to get better integrate into modern desktop.

Gcolor3 enables you to pick the color from any pixel on your screen. It also offers a palette, so that you can easily mix and match a couple of colors together.

When you have found the perfect combination of colors, naturally you want to save them. Gcolor3 allows you to conveniently save and retrieve colors.

By releasing version 2.4.0, Gcolor3 now is “Color Picker” with a new maintainer, a new icon, lots of new improvements, and many translation updates.

How to get Gcolor in Ubuntu:

The latest Gcolor so far is available as Flatpak package. You can either download the package from the link below:

or open terminal (Ctrl+Alt+T) and run following commands one by one to install the package:

sudo apt install flatpak

flatpak install flathub nl.hjdskes.gcolor3

To uninstall the software, run command:

flatpak uninstall nl.hjdskes.gcolor3

Prefer deb to the containerized flatpak package?
