Eu adicionei bibliotecas Qt4 PPA usando a resposta para issopergunta, mas quando executo estes comandos:

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

Eu recebo este erro:

However the following packages replace it:

Package libqtgui4 is not available, but is referred to by another package.

Não acho que esses erros estejam relacionados ao fato de você ter instalado o "ipython" ou não. Recebi o mesmo erro ("Não foi possível localizar o pacote libqt4-dev") durante a instalação de "libqt4-dev"(quero usar qt5 e meu ambiente éUbuntu22.04também). A solução que encontrei foi adicionar um novo "add-apt-repository":

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

então execute o comando:

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

Espero que isso seja útil para você.
