Newest release not found when trying to update a module

Hi, I'm trying to update matplotlib using the bash console by running

pip3.7 install --upgrade --user matplotlib==3.6.0

The response is

ERROR: No matching distribution found for matplotlib==3.6.0

The latest available release is 3.5.3. I also tried the above command without "==3.6.0" but this does not work either. Is there another way to update the module? Any version after 3.6.0 would be fine.

Check which versions of Python are supported for 3.5.3 and 3.6.0. It's likely that those later versions are not supported on Python 3.7
