sane 1.0.32 (from PPA) prevents installation of WineHQ
Please look in the thread from here for the details: https://forum.winehq.org/viewtopic.php?f=8&t=36119#p135871
It seems, the reason is, that perl is not multiarch, but sane seems to think so.
After reverting to the distro's version of sane, I could reinstall WinHQ in the end. But now I can't upgrade to sane 1.0.32. Follow the thread from here for the details: https://forum.winehq.org/viewtopic.php?f=8&t=36119#p135888
I discovered the Problem on Ubuntu 20.04. For testing I than tried this first in my backup machine, which is Ubuntu 18.04.
