Audacity audio editor and recorder is easy to install in Ubuntu Software via Snap package. For those prefer the classic deb package, the Ubuntu PPA has updated for the latest Audacity 3.0.2.
Since Audacity 3.0, it requires the development branch of wxWidgets toolkit 3.1.x. However, Ubuntu provides only the stable v3.0 series packages.
There are however known issues in the PPA build. When starting Audacity in Ubuntu 21.04 or Linux Mint 20, it will popup “An assertion failed” dialog, which indicates:
./src/widgets/FileConfig.cpp(98): assert “mDirty == false” failed in ~FileConfig().
Just click on “continue” button, and the software should start.
Another issue is that the app window slow to open. It takes a few seconds to start due to AlSA issues and warning. However, it works once app window opens!

Open terminal either from system application menu or by pressing Ctrl+Alt+T on keyboard. When terminal opens, run following commands one by one:
1.) Run command in terminal to add the Ubuntu PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/audacity
