Thank you very much ! Your command did not work in Spyder's console on the desktop, first because of the 3 at the end of pip, then because pressing the Y key at the prompt did not do anything. After googling how to force uninstall I found the command that worked for the desktop :
pip uninstall iPython -y (I did not have a local qtconsole package installed) In qemu, I typed this in a regular console since no console worked in Spyder : python3 -m pip uninstall qtconsole iPython Here the prompts accepted my Y presses. I then had to do (probably because I closed spyder while it was reporting the error messages for a github bug report) : killall spyder Then Spyder started successfully ! Too bad your instructions are not included in Spyder's error messages to explain to people like me who are not pros what to do to solve such a simple problem ! Anyway, thank you again ! P.S. : the mail bounced because this mail address I use for bug reports had not been used for too long, and I had to renew the password.
