In a virtual environment with python 3.9, have to modify requirements.txt

importlib_metadata
mapomatic==0.6
mthree==0.24
pylatexenc
qiskit==0.46.3
qiskit-aer
qiskit-terra>=0.21

it will install

qiskit-0.46.3 (the last one before qiskit 1.0)
qiskit-aer-0.14.2
qiskit-terra-0.46.3

and

from linear_solvers import NumPyLinearSolver, HHL

works without errors (after moult effort).
