News, Tutorials, Howtos for Ubuntu Linux
Linux world got some big updates, such as XFCE 4.20, RHEL 10.0 Beta, and Linux Mint 22.1 Beta, in last days. While, many free open-source apps also released updates recently you may care about.
And, here I’m going to introduce some of them for you. They include Audacity 3.7.1, GNU Octave 9.3.0, Scrcpy 3.1, VS Code 1.96, and TeXstudio 4.8.5.
Audacity audio editor announced 3.6.2 release a week ago, then version 3.6.3 a day ago with a quick-fix.
As you may know, Audacity 3.6.0 introduced new compressor and limiter effects, replacing the old ones. For those who prefer the classic effects, the new point release added a “Legacy” effects section, under “Effects” menu, that contains the old Limiter, Compressor and Classic Filters.
Audacity audio editor announced new major 3.6.0 release few days ago. Here are the new features and how to install guide for Ubuntu users.
The new release features new Master Effects. By clicking “Effects” button in app window, it will now show you Realtime Effects and Master Effects options for choice. While, the new Master Effects allows to apply effects to the entire project at once.
Audacity, the popular free open-source audio editor, release version 3.5.0 (then 3.5.1 with quick-fixes) few days ago.
Audacity 3.5.0 is a major release with new features. They include a new cloud-saving feature. By going to menu ‘File -> Save To Cloud …’, user can save Audacity project to audio.com via a free account. So, user can access the project from any other devices, and/or share and collaborate with others.
NOTE: this feature does NOT work in my PPA package, since it’s built with Debian upstream rule that disables network access! If you do prefer this feature, please leave comment below, or use the official AppImage package instead.
Audacity audio editor announced the first point release for the Audacity 3.4.0 feature release today!
The release can now built again in ARM devices and BSD. And, it has various stability and other fixes that 3.4.0 users are urged to upgrade to the new release.

Forgive me for the old image.

Audacity audio editor released version 3.3.3 a day ago.
The new release fixed the Filter Curve EQ and Graphic EQ scaling when resizing the dialog. Previously, resizing it only cause large blank area while leaving EQ unchanged.
The release also fixed audio.com upload flow. It added track title field which is required for upload, and audio.com link is opened immediately upon upload. However, anonymous uploads that was disabled in the last release is still NOT allowed.
Audacity offers official AppImage package available to download at the link below:
It’s a non-install package that runs in most Linux. Just right-click on it in file manager, go ‘Properties’ and add “Allow executing file as program” permission, finally, click Run it to open the audio editor.
Tip: Ubuntu 22.04 and higher, need to enable AppImage support first by running command below in terminal:
sudo apt install libfuse2
Audacity is also available to install as Flatpak package. Ubuntu user can press Ctrl+Alt+T on keyboard to open terminal, and run the 2 commands below one by one to get it.
First, run command to enable Flatpak support:
sudo apt install flatpak
Then, run command to install Audacity as Flatpak:
flatpak install https://dl.flathub.org/repo/appstream/org.audacityteam.Audacity.flatpakref
Flatpak takes so much disk space (2 GB+ in my case) for this single application, so here’s an unofficial PPA contains native .deb package for Ubuntu 22.04, Ubuntu 22.10, and Ubuntu 23.04. Support for Ubuntu 20.04 is still NOT available due to compile bug.
NOTE: the PPA follows the build rule from the Audacity package in Debian/Ubuntu repository, which disabled networking! Meaning there’s NO audio.com sharing!! If you do need this feature, please leave comment for request.
1. First, open terminal either by pressing Ctrl+Alt+T on keyboard, or by searching from start menu ‘Activities’ overview depends on your DE.
2. When terminal opens, paste the command below and hit run to add the PPA.
sudo add-apt-repository ppa:ubuntuhandbook1/audacity
Type user password when it asks (no asterisk feedback) and hit Enter to continue.
3. If an earlier version was installed via apt install command, you can then upgrade the package using Software Updater (Update Manager).
Or, just run command in terminal to install/update the Audacity .deb package:
sudo apt install audacity
NOTE: Linux Mint may need to run sudo apt update first.
Once installed, search for and open it from start menu or ‘Activities’ overview and enjoy!
For the AppImage, just remove the package file. For Flatpak, open terminal and run command:
flatpak uninstall --delete-data org.audacityteam.Audacity
And run flatpak uninstall --unused to free up disk space.
To uninstall the Audacity software packages installed from PPA, simply open terminal and run command:
sudo apt remove audacity audacity-date
Also, remove the Ubuntu PPA either by running command:
sudo add-apt-repository --remove ppa:ubuntuhandbook1/audacity
or by launching “Software & Updates” and removing source line under “other software” tab.
That’s all. Enjoy!
For those who prefer the classic .deb package format, I’ve revived the Ubuntu PPA for the latest Audacity audio editor packages.
I was previously maintaining a PPA for the Audacity packages. It was however discontinued. Because, the project depended its own fork of wxWidget library, that is hard to maintain. And, Debian/Ubuntu upstream even stopped updating (now revived) the software package due to policy changes.
Now, Audacity can be built with the wxWidget 3.2 library from Ubuntu’s system repositories. And, Debian/Ubuntu again keep updating the software package (v3.2.4 at the moment) in the new Distro releases.
So I decide to continue the PPA with the latest Audacity packages built against the rules from Debian upstream. And, now it’s updated to Audacity 3.7.0.
Audacity 3.3 installed as .deb package
For the release note, and the official AppImage package, see the Github Release page.
The PPA so far supports for Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 24.10 on both x86_86 and ARM CPU platforms.
1. First, open terminal either by pressing Ctrl+Alt+T on keyboard, or by searching from start menu ‘Activities’ overview depends on your DE.
2. When terminal opens, paste the command below and hit run to add the PPA.
sudo add-apt-repository ppa:ubuntuhandbook1/audacity
Type user password when it asks (no asterisk feedback) and hit Enter to continue.
3. If an earlier version was installed via apt install command, you can then upgrade the package using Software Updater (Update Manager).
Or, just run command in terminal to install/update the Audacity .deb package:
sudo apt install audacity
NOTE: Linux Mint may need to run sudo apt update first.
Once installed, search for and open it from start menu or ‘Activities’ overview and enjoy!
If you also installed Audacity as Flatpak, or create a shortcut for official AppImage, you may then have duplicated app icons. You can choose to either remove the other package, or start the .deb version from command line:
/usr/bin/audacity
To uninstall the Audacity software packages, simply open terminal and run command:
sudo apt remove audacity audacity-date
Also, remove the Ubuntu PPA either by running command:
sudo add-apt-repository --remove ppa:ubuntuhandbook1/audacity
or by launching “Software & Updates” and removing source line under “other software” tab.
That’s all. Enjoy!

It’s the 64-bit Appimage package that runs in most Linux Distributions. Without installing, it’s a single executable that launches the software via double-click.
It is incompatible with the GPL license. Use it at your own risk!
Other changes in Audacity 3.0.3 so far includes:
To get the Audacity Appimage, go to:
Once you get it, add executable permission in file Properties dialog. Then click run to open the editor:
