How to install openconnect-sso on Ubuntu 21.04

I would like to install openconnect-ssh. The install instructions from the project seem complex, I'm not sure what pipx is.

How do I install openconnect-sso on Ubuntu without using pipx and using native Ubuntu qt libraries?

I tried to install it using pip, but I got the following errors:

Во-первых, вам нужно установить зависимости Qt5 Python:

sudo apt установить python3-pyqt5 python3-pyqt5.qtwebengine

Затем вы устанавливаете openconnect-sso с помощью pip

pip установить openconnect-sso

После этого вы можете легко запустить приложение:
