Installing imgtool is not working

[lefebvresam]

If you install imgtool with:

sudo python3 mcuboot/scripts/setup.py install

And then do;

imgtool keygen -k filename.pem -t rsa-2048

You get:

Traceback (most recent call last):

    sys.exit(load_entry_point('imgtool==2.1.0', 'console_scripts', 'imgtool')())
