For reasons unknown, aMule, all-platform eMule P2P Client, is not included in Ubuntu 20.04 main repository.

While it’s available in previous Ubuntu repositories as well as the next Ubuntu 20.04 main repository, you can manually download the package and dependencies from Ubuntu 18.04 and install them manually in Ubuntu 20.04.

1.) Click download the amule package:

amule .deb

2.) Click download amule-common package:

amule-common .deb

3.) Click download amule-utils-gui package (optional):

amule-utils-gui .deb

4.) Finally download the libwxgtk3.0-0v5 package:

libwxgtk3.0-0v5 .deb

When downloading processes finished, open terminal (Ctrl+Alt+T) from system applications menu and run single command to install them:

sudo apt install ~/Downloads/amule*.deb ~/Downloads/libwxgtk*.deb

Once installed, launch the client from your system application menu and enjoy!

(Optional) To remove the amule package as well as dependencies, run command:

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 for testing. For any issue, report to this page.

Install Puddletag Python3 & PyQt5 version:

The new branch is still in development. Not all functions are implemented yet. And there may have bugs. Use it at your own risk!

If you still want to install the previous Python2 & Qt4 package, leave a comment and I’ll write in another tutorial.

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
