error: failed to commit transaction (conflicting files)
python-numpy: /usr/bin/f2py exists in filesystem
Errors occurred, no packages were upgraded.

So the error is due to python-numpy conflicting with the file /(usr/bin/f2py.

I've looked up in this forum and found this and this, and in both cases the bottom line is

The problem is that you installed numpy or some other package using sudo pip, which is something you must never do

This is a system I rarely use, so I can't really recall if I ever installed anything using pip. I might have done it, given that pip is installed to start with. But... I don't know.

Re: [SOLVED] Can't install flowblade

what does pacman -Qo /usr/bin/f2py  report?

Re: [SOLVED] Can't install flowblade

error: No package owns /usr/bin/f2py

Do I just nuke it?

Re: [SOLVED] Can't install flowblade

That is probably how I would handle it.    There is also a switch in pacman that will tell it to overwrite the file.  Either way works.
