I understand why /usr/lib64/ doesn't work right now on Ubuntu (that's a directory commonly used by Fedora and Red Hat distros).
I don't understand why /usr/lib/sane/ doesn't work according to the comments here. When sane-backends was converted to multiarch, a patch was added that I think was supposed to enable /usr/lib/sane/ to still be supported. https://jff.email/cgit/sane-backends.git/commit/?id=ac1cb335be https://jff.email/cgit/sane-backends.git/tree/debian/patches/0125-multiarch_dll_search_path.patch If that patch worked, then maybe it makes sense to just add /usr/lib64/ there too. I don't have a scanner myself to test any of this. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1728012 Title: Many 3rd party scanner drivers are broken by a sane change Status in sane-backends package in Ubuntu: Confirmed Bug description: Many scanners can no more be used since sane has changed something: The 3rd-party plug-in the vendor provides as .deb package will still install. But the scanner is no more recognized. Scanners that are affected are(besides others): - Epson Perfection V10 - Epson Perfection V1000 - Epson WorkForce GT-1500 - Brother MFC-8510DN - Epson Perfection V33 It is to note that the probability that the scanner manufacturers fix things others broke is below 100%.
