I created a new Ubuntu VM with 22.04.2. To install the "guest additions" so that the Ubuntu window could be resized ot something useful, I had to run
sudo apt-get install gcc make perl I installed pip with sudo apt install python3-pip Then I installed Leo from PyPi: python3 -m pip install --user leo Leo failed to run: python3 -m leo.core.runLeo The error message included a line I've seen before: qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. I remembered that I've encountered this before and solved it by installing a .so library. It's some kind of a packaging error by Ubuntu. I couldn't find any notes about doing so, so I searched the internet, but the best-looking solution I tried didn't fix the problem. Rather than spend more time, I just installed PyQt6 and after this Leo runs: python3 -m pip install --user pyqt6 To get the viewrendered3 plugin to work, you will also need to install the WebEngine for PyQt6: python3 -m install --user PyQt6-WebEngine On Sunday, May 7, 2023 at 8:35:50 AM UTC-4 Thomas Passin wrote: > Someone else recently had problems on Ubuntu 22 LTS.
