@gunnarhj I tested the ppa and bionic-propsed a machine with fresh clean install of bionic with CanoScan LIDE 100. The issue is *not* fixed on this machine.
Here are the details of my testing: I switched back and forth between distro-default, ppa and bionic- proposed versions of libsane-common (and libsane1), restarted the machine etc. PPA After adding ppa, I run apt upgrade which updated these libsane-common, libsane1, sane-utils packages to ``` libsane-common/bionic,bionic,now 1.0.27-1~experimental3ubuntu2.2~ppa all [installed,automatic] libsane1/bionic,now 1.0.27-1~experimental3ubuntu2.2~ppa amd64 [installed,automatic] sane-utils/bionic,now 1.0.27-1~experimental3ubuntu2.2~ppa amd64 [installed,automatic] ``` I did a test scan. Colored bar still appeared. I restarted the system (or should I have restarted some sane service?). Tried scanning again. Issue still exists. To go back to distro default, I removed the ppa and libsane-common. This removed a whole bunch of dependencies including ubuntu-desktop and simple-scan. Reinstalling ubuntu-desktop brought libsane-common etc back. Scanned a page again to see if there are any surprises. None. The problem still existed. BIONIC-PROPOSED I enabled bionic-proposed channel repo. It showed a whole bunch of updates. I had to pin the packages and install libsane-common/bionic- proposed and sane-utils/bionic-proposed. package versions after this: libsane-common/bionic-proposed,bionic-proposed,now 1.0.27-1~experimental3ubuntu2.2 all [installed] libsane1/bionic-proposed,now 1.0.27-1~experimental3ubuntu2.2 amd64 [installed] sane-utils/bionic-proposed,now 1.0.27-1~experimental3ubuntu2.2 amd64 [installed] The problem persisted during immediate scan and after a restart. -- 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/1731459 Title: genesys_gl847 scanners produce a black band in scanned images on Ubuntu 17.10+, 18.04 LTS and 18.10 Cosmic cuttlefish Status in sane-backends: Unknown Status in sane-backends package in Ubuntu: Fix Released Status in sane-backends source package in Bionic: Fix Committed Status in sane-backends source package in Disco: Fix Committed Status in sane-backends package in Debian: Unknown Bug description: [Impact] When using a Genesys GL847 scanner, the documents get disfigured by a discolored bar. The proposed uploads should fix the issue. They are available in this PPA: https://launchpad.net/~gunnarhj/+archive/ubuntu/sane-backends [Test case] 1. Install the libsane (libsane1 in bionic), libsane-common and sane-utils packages from {bionic,disco]-proposed. 2. Use an affected device to scan, and find that the issue is no longer present. [Regression risk] Upstream commit, focused bug fix => low regression risk [Original description] On Windows it works but on my Ubuntu 17.10, 18.04 and 18.10 I see a black band on scanned image.
