In reference to Bug 1180037 - X11:Utilities/WoeUSB: Version upgrade:

WoeUSB is no longer supported. Good way is to upgrade to WoeUSB-ng.

1. Uninstall WoeUSB if already installed.
2. Add repo (for Leap 15.2, change according to your OS version):
zypper addrepo
3. Update pip3. Version 10.0.1 doesn't work, version 20.2.3 work Ok.
4. Install p7zip, p7zip-full, python3-termcolor, python3-wxPython, python3-numpy.
5. You may want to update "pillow" package.
6. You may want to install python3-pip-wheel (python3-wheel? python3-setuptools-wheel?).
7. Install WoeUSB-ng:
sudo pip3 install WoeUSB-ng

It were nice to get WoeUSB-ng packaged.
