I installed ROS noetic for ubuntu 20.04 following the steps presented on the next page: http://wiki.ros.org/noetic/Installation/Ubuntu, but the rqt command is not working for me and it always shows the following error

problem solved by uninstalling PyQt5 and PyQt5-sip with pip3

This helps me too, thanks

same here :) When trying to reinstall, pyqt5 was already/still present as system-wide installation, while pyqt5-sip reinstalled as user without breaking rqt plugins. Probably some outdated user-based installation of pyqt5 interfering with the system-wide version?
