sudo apt update
sudo apt install qt4-dev-tools libqt4-dev libqtcore4 libqtgui4

Recibo este error:

However the following packages replace it:

No creo que estos errores estén relacionados con si instaló "ipython" o no. Tengo el mismo error("No se puede localizar el paquete libqt4-dev") al instalar "libqt4-dev" (quiero usar qt5 y mi entorno esubuntu22.04también). La solución que encontré fue agregar un nuevo "add-apt-repository":

$sudo add-apt-repository ppa:ubuntuhandbook1/ppa
$sudo apt-get update

luego ejecuta el comando:

$sudo apt-get install qt4-dev-tools libqt4-dev libqtcore4 libqtgui4

Espero que esto sea útil para usted.
