There are also known issues that ppd browsing is failing sometimes while doing hp-setup in Ubuntu 20.10. Basically few times it is failing to fetch ppd list from cups server.

And not sure if it’s only me or for everyone, while it works on Ubuntu 20.10, HPLIP 3.20.11 does not install on my Ubuntu 20.04 since it tries to install the old python-pyqt5 as dependency library.

1. To install the software, download the package “hplip-3.20.11.run” from the link below:
