Since Ubuntu 20.04 has dropped Qt4 and old Python2 libraries, Puddletag audio tag editor is no longer available to install.
There are a few alternatives (e.g., easytag and kid3 tag editor) available in main Ubuntu repositories.
If you persist in installing Puddletag in Ubuntu 20.04, the development of PyQt5 & Python 3 branch has started. And I’ve uploaded it into PPA.
Install Puddletag 2.0.1 in Ubuntu 20.04:
1.) Open terminal either from system application menu or by pressing Ctrl+Alt+T on keyboard. When terminal opens, run command to add the PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/apps
Type user password (no asterisk feedback) when it prompts and hit Enter to continue.
2.) Then refresh system package cache and install the editor via command:
sudo apt update sudo apt install puddletag
Uninstall Puddletag & PPA:
To remove the PPA, either go to Software & Updates > Other Software, or run command:
sudo add-apt-repository --remove ppa:ubuntuhandbook1/apps
And remove puddletag by running command:
sudo apt remove --autoremove puddletag
