@tom-rausner: This should not affect your ability to scan. As long as libsane1:amd64 is installed (and it has to be installed otherwise this error won't be given), you should be able to scan using normal scanner application. (Unless you need a 32-bit driver, then you'll have to uninstall libsane1:amd64 and install libsane1:i386 along with i386 version of scanner application instead)
BTW, this seems to be reported at Debian's bugtracker already. However, as the version which this package in Ubuntu is based upon is in experimental, we'll have to see if this will be fixed anytime soon in Debian. ** Bug watch added: Debian Bug tracker #880391 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=880391 ** Also affects: sane-backends (Debian) via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=880391 Importance: Unknown Status: Unknown -- 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/1725928 Title: package libsane1 1.0.27-1~experimental2ubuntu1: multiarch packages with differing files Status in sane-backends package in Ubuntu: Confirmed Status in sane-backends package in Debian: Unknown Bug description: apport error this morning.
