Hi

Trying to install PyQt5, I get the following message :

I understand I should check the logs to get more information. However I don't know their localisation.

Thanks to anybody indicating where I can check the logs.

I running Python 3.8.10 under Ubuntu VERSION="20.04.6 LTS (Focal Fossa)"

You can try installing the pyqt5 package with
sudo apt install python3-pyqt5

I recently installed PyQt5 and PyQt6. I'll admit up front that I had to look up this stuff. Searching my command history I see that I used this for PyQt5:

sudo apt-get install python3-pyqt5

And I have written Python scripts with PyQt5, so it must have worked.

I used the same command for PyQt6:

sudo apt install python3-pyqt6

But that didn't work and I had to use this instead:

pip3 install pyqt6

Hi

I installed using

sudo apt-get install python3-pyqt5

and it works.

Thank you to both of you
