I am using msys2 from PortableApps, under Win 10.
When I try a full upgrade with pacman -Syuu, I get
:: Synchronizing package databases...

It looks to me that I would not be able to retain python2-qt5.
Is there any workaround for that? I could keep answering no, but I guess I should give up at some point.
Note 1: I wonder if there is any connection with the packages reported as requiring update and Msys2 with python 3.8: ImportError: cannot import name 'open_code' from 'io'
Note 2: I never installed any package with pip, but always with pacman.
