PyPlot cannot be used on Julia 1.7.2

[kzapfe]

I have just updated/upgraded my whole system and now I have Julia 1.7.2
I have updated the packages of Julia and they seem to be downloaded fine, and there are no complaints after using the
add PyPlot on the Pkg interface.
But If I try:

using PyPlot

I get the following error:

using PyPlot, DelimitedFiles, JLD

┌ Info: Precompiling PyPlot [d330b81b-6aea-500a-939a-2ce795aea3ee]
└ @ Base loading.jl:1423

signal (6): Abortado
in expression starting at /home/karel/.julia/packages/PyPlot/XaELc/src/PyPlot.jl:4

And then the usual gibberish ending with:

Could you post the full error message? I can't reproduce this in a fresh environment.

Was there an error or warning when you built PyCall?

It works fine for me… maybe it is a problem with your Python installation?
