I posted it on Reddit about being unable to scan with Epson EcoTank L575 printer and forgot to post here, but the problem persist. (here). I tried reinstalling the packages and even the updated packages, that still do not have a Fedora 33 version, made available after I posted. I downloaded some source to try to compile it, but can’t solve dependencies.
Furthermore, I tested as suggest paid software, VueScan. It is available via Flatpak, but did not work as a flatpak. It worked when I downloaded a “portable” version and ran it with root privileges. VueScan is a paid software, so it is not a solution for my friend.
VueScan has the drive embeded in itself which, for what I can tell from the imagescan-bundle package, is what is done with the Epson drivers for the scanner also.
