I cannot reproduce this issue with a fresh Ubuntu 18.04.3 VM. Please make sure you are using all packages from Ubuntu repository and not from PyPI.
In any case, it would be a bug in spyder, not in qtbase or pyqt5. ** Attachment added: "VirtualBox_Ubuntu 18.04.3 LTS_21_08_2019_21_00_23.png" https://bugs.launchpad.net/ubuntu/+source/pyqt5/+bug/1832019/+attachment/5283795/+files/VirtualBox_Ubuntu%2018.04.3%20LTS_21_08_2019_21_00_23.png ** Changed in: qtbase-opensource-src (Ubuntu) Status: New => Invalid ** Changed in: pyqt5 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1832019 Title: Error when going to 'Tools -> Preferences -> Keyboard shortcuts' in Spyder3 in Bionic Status in pyqt5 package in Ubuntu: Invalid Status in qtbase-opensource-src package in Ubuntu: Invalid Status in spyder package in Ubuntu: New Bug description: In Ubuntu 18.04 LTS Steps: 1.
