PythonPlot not showing anything

Hi,
I’ve just installed julia 1.12.5 on a new ubuntu box. First thing I tried was to install PythonPlot, and then on the repl

using PythonPlot
plot(rand(1000),randn(1000))

displays nothing at all. In old Pyplot.jl that opened a qt window with the plot, but not here. It just reports that a fiigure has been created but doesn’t show it…
